DETAILED DESCRIPTION OF THE INVENTION 
1. Industrial Field of the Invention 
The present invention relates to a modified aromatic polycarbonate resin, a 
molded article thereof, a composition thereof, and a substituted phenol 
compound used for the modification of an aromatic polycarbonate resin. It 
also relates to a modified aromatic polyester carbonate resin and a 
modified polyarylate resin. In particular, it relates to a modified 
aromatic polycarbonate resin which retains the excellent transparency and 
mechanical properties of an aromatic polycarbonate resin and has improved 
melt fluidity and tracking resistance and a molded article thereof. 
2. Prior Art of the Invention 
As a typical aromatic polycarbonate resin, an aromatic polycarbonate resin 
obtained by reacting 2,2-bis(4-hydroxyphenyl)propane (generally called 
bisphenol A) with phosgene or a carbonate precursor such as diphenyl 
carbonate is known and mass-produced. This polycarbonate resin is widely 
used in a variety of fields since a molded article thereof has excellent 
properties such as excellence in transparency, heat resistance and 
dimensional accuracy. In recent years, the polycarbonate resin is also 
widely used as a substrate for information recording media in the field of 
an optical disk. 
With a recent downsizing tendency of household utensils, home electric 
appliances, video units and their accessories and audio units and their 
accessories, it is now desired to develop an aromatic polycarbonate resin 
which is much more improved in melt fluidity and replicating properties. 
In the field of electric appliances, it is also demanded to develop an 
aromatic polycarbonate resin having improved tracking resistance. 
For improving an aromatic polycarbonate resin in the melt fluidity, there 
is proposed a method in which the average molecular weight of the aromatic 
polycarbonate resin is decreased to the lowest level possible, a method in 
which a plasticizer is added, a method in which the polymer terminal is 
provided with a long-chain aliphatic hydrocarbon substituent or a method 
in which a polymer blend is formed. The defect with these methods is that 
the excellent properties inherent to an aromatic polycarbonate resin 
cannot be retained, that is, the physical properties are decreased or the 
transparency is impaired. 
SUMMARY OF THE INVENTION 
It is a first object of the present invention to provide a modified 
aromatic polycarbonate resin of which the melt fluidity is improved 
without substantially impairing the excellent properties inherent to a 
polycarbonate resin such as transparency, heat resistance and dimensional 
stability. 
It is a second object of the present invention to provide a modified 
aromatic polycarbonate resin which has improved electric insulation 
properties, particularly improved tracking resistance, while it retains 
the excellent properties of a polycarbonate resin described above. 
It is a third object of the present invention to provide a modified 
aromatic polycarbonate resin having excellent properties as a raw 
structural material for a variety of electric and electronic parts and 
optical parts, and a molded article thereof. 
It is further another object of the present invention to provide a modified 
aromatic polyestercarbonate resin and a modified polyarylate resin of 
which the melt fluidity is improved with retaining the excellent 
properties inherent to an aromatic polycarbonate resin and a polyarylate 
resin, such as transparency and mechanical strength. 
It is still further another object of the present invention to provide a 
substituted phenol compound used as a modifier for obtaining the above 
modified aromatic polycarbonate resin, an improved aromatic polyester 
carbonate resin and an improved polyarylate resin.

Most of known aromatic polycarbonate resins generally have terminals having 
a phenyloxy group or an alkyl-substituted phenyloxy group. These terminal 
groups contribute to the adjustment of the polymerization degree and the 
improvement of the polymer in heat resistance. In the present invention, 
the specifically structured, substituted phenyloxy group of the formula 
(1) is present in an amount of at least 5 mol %, preferably 7 to 90 mol %, 
of the total amount of terminals, whereby the melt fluidity and the 
processability are improved without impairing the excellent properties of 
an aromatic polycarbonate resin, such as transparency, heat resistance and 
dimensional stability, and moreover, the electric properties are improved. 
The substituted phenyloxy group of the formula (1) has a characteristic 
feature in that the phenyloxy group has a structure in which the 
oxyalkylene ester group represented by Q or its polymer residue is 
substituted by the phenyloxy group. 
The present invention will be detailed hereinafter. 
In the aromatic polycarbonate resin, at least 5 mol % of the total 
terminals thereof is to be substituted with the substituted phenyloxy 
group of the formula (1) can be selected from known polycarbonate resins 
or industrially produced polycarbonate resins. That is, the skeleton of 
the aromatic polycarbonate resin of the present invention can be a polymer 
obtained by the reaction between a dihydric phenol and a carbonate 
precursor. 
The dihydric phenol used for the production of the aromatic polycarbonate 
resin includes monocyclic and bicyclic dihydric phenols. Specific examples 
of the monocyclic dihydric phenol include hydroquinone and resorcinol. 
Specific examples of the bicyclic phenol include compounds of the formula 
(III), 
##STR6## 
wherein each of R.sup.4, R.sup.5, R.sup.6 and R.sup.7 is independently a 
hydrogen atom, a halogen atom, an aliphatic hydrocarbon group having 1 to

atoms, a cycloalkylene group having 6 to 10 carbon atoms, a 
cycloalkylidene group having 6 to 10 carbon atoms or a phenyl-substituted 
alkylidene group having 2 to 6 carbon atoms. 
Specific examples of the above dihydric phenols for forming the aromatic 
polycarbonate resin include hydroquinone, resorcin, 
4,4'-dihydroxydiphenyl, bis(4-hydroxyphenyl)methane, 
1,1-bis(4-hydroxyphenyl)ethane, 2,2-bis(4-hydroxyphenyl)propane (generally 
called bisphenol A), 2,2-bis(3-methyl-4-hydroxyphenyl)propane, 
1,1-bis(4-hydroxyphenyl)cyclohexane, 
2,2-bis(3-phenyl-4-hydroxyphenyl)propane, 
2,2-bis(3-isopropyl-4-hydroxyphenyl)propane, 
2,2-bis(4-hydroxyphenyl)butane, 
2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane, 
2,2-bis(3,5-dibromo-4-hydroxyphenyl)propane, 
4,4'-dihydroxydiphenylsulfone, 4,4'-dihydroxydiphenylsulfoxide, 
4,4'-dihydroxydiphenylsulfide, 
3,3'-dimethyl-4,4'-dihydroxydiphenylsulfide, 4,4'-dihydroxydiphenyloxide, 
9,9-bis(4-hydroxyphenyl)fluorene, 
1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane and 
1,3-bis(4-hydroxyphenyl)-5,7-dimethyladamantane. 
Of the above dihydric phenols, preferred are 
2,2-bis(4-hydroxyphenyl)propane (bisphenol A), 
2,2-bis(3-methyl-4-hydroxyphenyl)propane, 
1,1-bis(4-hydroxyphenyl)cyclohexane, 
2,2-bis(3-phenyl-4-hydroxyphenyl)propane, 
2,2-bis(3-isopropyl-4-hydroxyphenyl)propane. 
2,2-bis(4-hydroxyphenyl)butane, 9,9-bis(4-hydroxyphenyl)fluorene, 
1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane and 
1,3-bis(4-hydroxyphenyl)-5,7-dimethyladamantane. 
Further, in view of practical use and physical properties, more preferred 
are bisphenol A, 1,1-bis(4-hydroxyphenyl)cyclohexane, 
9,9,-bis(4-hydroxyphenyl)fluorene, 
1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane and 
1,3-bis(4-hydroxyphenyl)-5,7-dimethyladamantane. The above dihydric 
phenols may be used alone or in combination. Further, a small amount of a 
trifunctional compound may be used as a branching agent, and a small 
amount of an aliphatic difunctional compound may be used in combination. 
Above all, bisphenol A is preferred for the preparation of the aromatic 
polycarbonate resin of the invention. 
A study of the present inventors has further revealed that the modified 
aromatic polycarbonate resin obtained by the modification of an aromatic 
polycarbonate resin obtained from 
1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane as a dihydric phenol 
is excellent in moldability and that a molded article from the modified 
aromatic polycarbonate resin is excellent in heat resistance, transparency 
and mechanical properties. Therefore, the above resin gives a molded 
article suitable for use in the optical field where heat resistance is 
required. 
The aromatic polycarbonate resin can be produced by the reaction between 
the above dihydric phenol and a carbonate precursor. Examples of the 
carbonate precursor include phosgene, phosgene dimer, phosgene trimer and 
bischloroformates of the above dihydric phenols. Above all, phosgene is 
preferred. 
The aromatic polycarbonate resin can be produced from the dihydric phenol 
and the carbonate precursor, for example, by a generally employed method 
in which the dihydric phenol is allowed to react with the carbonate 
precursor such as phosgene. The reaction between the dihydric phenol and 
phosgene is generally carried out in the presence of an acid scavenger and 
a solvent. The acid scavenger is selected, for example, from alkali metal 
hydroxides such as sodium hydroxide and potassium hydroxide and pyridine. 
The solvent is selected, for example, from halogenated hydrocarbons such 
as methylene chloride and chlorobenzene. Further, a catalyst may be used 
for the promotion of the reaction, and the catalyst is selected from 
tertiary amines and quaternary ammonium. The reaction temperature is 
generally between 0.degree. and 40.degree. C., and the reaction time is 
several minutes to 5 hours. During the reaction, preferably, the pH is 
generally maintained at least 10. 
The modified aromatic polycarbonate resin of the present invention can be 
produced as follows. When the above aromatic polycarbonate resin is 
produced, a monofunctional phenol compound is allowed to be co-present 
together with the dihydric phenol compound and the carbonate precursor so 
that the substituted phenyloxy group of the formula (1) bonds to a 
terminal group. 
That is, a typical compound used for the forming the terminal group of the 
formula (I) is a substituted phenol compound of the formula (II). 
##STR7## 
In the formula (II), X, P and Q are as defined in the formula (I). 
The substituted phenol compound of the above formula (II) is a 
monofunctional compound having one phenolic hydroxyl group, and it works 
as a terminal-forming agent and bonds to a terminal group. For obtaining 
the modified aromatic polycarbonate resin of the present invention, other 
monofunctional phenol compound may be used in combination with the 
substituted phenol compound of the formula (II). The "other monofunctional 
phenol compound" has the following formula (IV). 
##STR8## 
wherein X' is a halogen atom or an aliphatic hydrocarbon group having 1 to 
10 carbon atoms, and p' is an integer of 0 to 5. 
Specific examples of the monofunctional phenol compound of the formula (IV) 
include phenol, p-tert-butylphenol, p-cumylphenol and isooctylphenol. 
When the modified aromatic polycarbonate resin of the present invention is 
produced, the amount of the substituted phenol compound of the formula 
(II), the amount of the monofunctional phenol compound of the formula (IV) 
and the proportions of these phenol compounds are determined on the basis 
of the kind of the polycarbonate resin, the kind of the terminal group, 
the polymerization degree and desired properties. 
In the modified aromatic polycarbonate resin of the present invention, the 
substituted phenyloxy group of the formula (I) is present in an amount of 
at least 5 mol %, preferably 7 to 90 mol %, particularly preferably 10 to 
80 mol %, of the total amount of terminal groups of the modified aromatic 
polycarbonate resin. The substituted phenyloxy group of the formula (I) is 
introduced into the terminal of the polymer owing to the use of-the 
substituted phenol compound of the formula (II). The modified aromatic 
polycarbonate resin of the present invention contains the substituted 
phenyloxy group of the formula (I) in the above-specified amount, while 
the remaining terminals are not specially limited. However, the remaining 
terminals preferably have terminal groups derived from the monofunctional 
phenol compound of the formula (IV). 
The easiest method for the production of the modified aromatic 
polycarbonate resin of the present invention is a method in which the 
substituted phenol compound of the formula (II) is added to raw material 
during the polymerization carried out for forming the aromatic 
polycarbonate resin. 
The modified aromatic polycarbonate resin of the present invention may be 
also produced by another method in which the polycarbonate resin is 
synthesized and then a reactive compound is further added to the 
synthesized polycarbonate resin to obtain the modified polycarbonate resin 
containing the substituted phenyloxy group of the formula (I) as a 
terminal group. 
Further, there is another method in which a reactive compound is added to 
the modified aromatic polycarbonate resin obtained by adding the compound 
of the formula (II) during the polymerization thereby to convert the 
terminal group to another terminal group which is included in the 
substituted phenyloxy group of the formula (I). As described above, there 
may be employed the above method in which the modified aromatic 
polycarbonate resin is once produced and then an intended terminal group 
is imparted by a post-treatment. (This method will be sometimes referred 
to as "post-treatment method" hereinafter). 
In the above method, for example, the compound of the above formula (II) 
wherein W.sup.1 is a hydrogen atom is used to obtain a modified aromatic 
polycarbonate resin having said compound as a terminal group, and then 
the-terminal alcoholic hydroxyl group of the compound of the formula (II) 
is blocked in the form of a carboxylic ester 
##STR9## 
or a carbonate ester 
##STR10## 
This blocking can be carried out by reacting carboxylic acid chloride or 
chloroformate ester with the above modified aromatic polycarbonate resin. 
The carboxylic acid chloride used above has the formula of ClCOR.sup.1 in 
which R.sup.1 is a monovalent hydrocarbon group having 1 to 10, preferably 
1 to 5, carbon atoms, an alicyclic hydrocarbon group having 4 to 8, 
preferably 5 to 6, carbon atoms or an aromatic hydrocarbon group having 6 
to 15, preferably 6 to 12, carbon atoms as defined in the above formulae 
(I) and (II). The above chloroformate ester has the formula of 
ClOCOOR.sup.2 in which R.sup.2 is selected from those hydrocarbon groups 
specified concerning the above R.sup.1. 
When the molecular weight of the above-obtained modified aromatic 
polycarbonate resin is too small, the modified aromatic polycarbonate 
resin is fragile and cannot be practically used. When a solution of 0.7 g 
of the modified aromatic polycarbonate resin in 100 ml of methylene 
chloride is measured for a specific viscosity at 20.degree. C. to show at 
least 0.165, the modified aromatic polycarbonate resin gives a molded 
article having excellent properties. The above specific viscosity is 
preferably 0.229 to 0.539, particularly preferably 0.264 to 0.451. 
The modified aromatic polycarbonate resin of the present invention can be 
molded by any one of an injection molding method, a compression molding 
method, an extrusion molding method and a solution casting method. The 
modified aromatic polycarbonate resin of the present invention may contain 
additives such as a heat stabilizer, an antioxidant, a light stabilizer, a 
colorant, an antistatic agent, a lubricant and a mold release agent and 
inorganic fillers such as a glass fiber, glass beads, a carbon fiber, a 
metal fiber, talc and silica. Further, it may be used as a blend with 
other polycarbonate resin or other thermoplastic resin. 
The modified aromatic polycarbonate resin according to the present 
invention has remarkably improved melt fluidity while it retains the 
excellent transparency, heat resistance and mechanical properties inherent 
to an aromatic polycarbonate resin. It can be also applied to a 
low-temperature high-cycle molding, and it has remarkably improved 
tracking resistance. 
The modified aromatic polycarbonate resin of the present invention that has 
particularly excellent properties and the use thereof will be explained 
hereinafter. 
In general, a molded article from the modified aromatic polycarbonate resin 
is excellent in transparency, and it is also excellent in optical 
properties. 
When at least one of the following materials is used as the dihydric phenol 
for the production of the modified aromatic polycarbonate resin, a molded 
article from the modified aromatic polycarbonate resin is excellent in 
optical properties and particularly has a small birefringence. That is, 
the raw materials as the dihydric phenol are 
2,2-bis(3-methyl-4-hydroxyphenyl)propane, 
1,1-bis(3-methyl-4-hydroxyphenyl)cyclohexane, 
1,1-bis(4-hydroxyphenyl)-1-phenylethane, 
1,1-bis(3-methyl-4-hydroxyphenyl)-1-phenylethane, 
2,2-bis(3-phenyl-4-hydroxyphenyl)propane, 4,4'-dihydroxytetraphenylethane, 
2,2-bis(4-hydroxyphenyl)butane, 9,9-bis(4-hydroxyphenyl)fluorene, 
1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane, 
2,2-bis(3-isopropyl-4-hydroxyphenyl)propane and 
1,3-bis(4-hydroxyphenyl)-5,7-dimethyladamantane. Therefore, a molded 
article produced from the above modified aromatic polycarbonate resin in a 
flat form is applicable to the field where a low birefringence is 
required. A molded article from the above modified aromatic polycarbonate 
resin is hence suitable for use as a structural material or a functional 
material for an optical part such as a flat panel for a liquid crystal 
unit, an optical card, an optical disk, an optical fiber, an optical 
waveguide path, a connector, various lenses, a prism and a film. 
Further, when 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane is used 
as the dihydric phenol, the modified aromatic polycarbonate resin is 
excellent over any other resin in heat resistance and a photoelasticity 
constant and can be preferably used for the production of a lens for a 
lamp. Further, the above modified aromatic polycarbonate resin can be also 
used for the production of a substrate for an optical recording medium. 
For the use of the above modified aromatic polycarbonate resin for the 
production of a substrate for an optical recording medium, preferred is 
the modified aromatic polycarbonate of which the specific viscosity (a) 
and the following constant (b) satisfy the following expressions. 
EQU 0.23.ltoreq..eta..sub.sp .ltoreq.0.37 (a) 
EQU 30.ltoreq.N.ltoreq.60 (b) 
wherein .eta..sub.sp is a specific viscosity of the modified aromatic 
polycarbonate resin and n is a proportion (%) of an ester unit 
##STR11## 
of the substituted phenyloxy group of the formula (I) based on the total 
molar amount of the dihydric phenol unit and the above ester unit in the 
modified aromatic polycarbonate resin. 
Further, when the modified aromatic polycarbonate resin of the present 
invention is mixed with a filler of glass having a refractive index of 
which the difference from the refractive index of the modified aromatic 
polycarbonate resin is within a predetermined range, the mixture gives a 
resin composition having improved transparency and excellent properties. 
According to the present invention, therefore, there is provided a resin 
composition comprising 40 to 95% by weight of the modified aromatic 
polycarbonate resin of the present invention and 60 to 5% by weight of a 
filler of glass having a refractive index of which the difference from 
that of the modified aromatic polycarbonate resin is 0.01 or less, and a 
molded article formed therefrom. 
The refractive index difference between the modified aromatic polycarbonate 
resin and the above filler of glass is 0.01 or less, preferably 0.005 or 
less. When this difference exceeds 0.01, the transparency decreases. The 
filler of glass may have any one of the forms that can be generally 
applied to a thermoplastic resin such as a fiber, granules, flakes, 
plates. When the filler has the form of a fiber, preferably, the diameter 
is 3 to 25 .mu.m and the fiber length in a molded article is approximately 
0.02 to 0.5 mm. Further, the filler of glass may be surface-treated with a 
silane-coupling agent for increasing the affinity with the resin, and it 
may be also subjected to a binding treatment with an epoxy resin, an 
acrylic resin or a urethane resin for improving the handing properties. 
The amount of the filler of glass is 5 to 60% by weight, preferably 10 to 
55% by weight. When this amount is less than 5% by weight, it is difficult 
to obtain a sufficient effect on the reinforcement with glass. When it is 
more than 60% by weight, undesirably, the moldability of the composition 
decreases. 
The above resin composition can be produced by any method. For example, it 
can be produced by a method in which the modified aromatic polycarbonate 
resin and the filler of glass are dry-blended with a tumbler, a super 
mixer or Nauter mixer and then pelletized with an extruder, or a method in 
which the modified aromatic polycarbonate resin and other additive are 
mixed in advance and then the mixture and a glass fiber are co-extruded to 
pelletize them. The resin composition can be molded by any one of an 
injection molding method, a compression molding method and an extrusion 
molding method. 
The above resin composition may contain a variety of other heat stabilizers 
and antioxidants as required. Examples of the heat stabilizers include 
triesters, diesters and monoesters of phosphorous acid such as triphenyl 
phosphite, trisnonylphenyl phosphite, 
tris(2,4-di-tert-butylphenyl)phosphite, tridecyl phosphite, trioctyl 
phosphite, trioctadecyl phosphite, didecylmonophenyl phosphite, 
dioctylmonophenyl phosphite, diisopropylmonophenyl phosphite, 
monobutyldiphenyl phosphite, monodecyldiphenyl phosphite, 
monooctyldiphenyl phosphite, 
bis(2,6-di-tert-butyl-4-methylphenyl)pentaerythritol diphosphite, 
2,2-methylenebis(4,6-di-tert-butylphenyl)octyl phosphite, 
bis(nonylphenyl)pentaerythritol diphosphite, 
bis(2,4-di-tert-butylphenyl)pentaerythritol diphosphite and 
tetrakis(2,4-di-tert-butylphenyl)-4,4-diphenylene phosphonate. These heat 
stabilizers may be used alone or in combination. Examples of the 
antioxidants include phenol-containing antioxidants such as triethylene 
glycol-bis[3-(3-tert-butyl-5-methyl-4-hydroxyphenyl)propionate, 
1,6-hdexanediol-bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], 
pentaerythritol-tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], 
octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, 
1,3,5-trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene, 
N,N-hexamethylenebis(3,5-di-tert-butyl-4-hydroxyhydrocinnamide), 
3,5-di-tert-butyl-4-hydroxybenzylphosphonate-diethyl ester, 
tris(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanurate and 
3,9-bis{1,1-dimethyl-2-[.beta.-(3-tert-butyl-4-hydroxy-5-methylphenyl)prop 
ionyloxy]ethyl}-2,4,8,10-tetraoxaspiro(5,5)undecane. 
The amount of the above heat stabilizer and the antioxidant based on the 
modified aromatic polycarbonate resin is properly 0.00005 to 0.05% by 
weight. Further, the above resin composition may contain a higher fatty 
acid ester of a polyhydric alcohol. The fatty acid ester includes whole 
esters and partial esters of saturated aliphatic monocarboxylic acids 
having 8 to 22 carbon atoms with glycols, glycerol and pentaerythritol. 
The amount of the fatty acid ester is preferably approximately 0.001 to 
0.2% by weight The above resin composition may further contain additives 
such as a light stabilizer, a colorant, an antistatic agent and a 
lubricant. Further, the above resin composition may contain other 
polycarbonate resin and other thermoplastic resin. 
The above resin composition containing a filler of glass has improved 
transparency, and hence can be remarkably suitably used for the production 
of molded articles in the fields of automotive parts, construction and 
electric and electronic parts. 
[II] Substituted phenol compound and method for the production thereof: 
The substituted phenol compound of the formula (II) used for the formation 
of a terminal group of the modified aromatic polycarbonate resin of the 
present invention and the method for the production thereof will be 
explained hereinafter. 
The substituted phenol compound of the formula (II) is classified into a 
compound of the following formula (II-a) and a compound of the following 
formula (II-b) on the basis of its structures and synthesis methods. 
##STR12## 
In the above formulae (II-a) and (II-b), X, p, Y, Z, OW.sup.2, W.sup.2, m 
and n have the following meanings. 
X is a halogen atom or a monovalent hydrocarbon group having 1 to 10, 
preferably 1 to 5, carbon atoms. 
p is an integer of 0 to 4. 
Y is a divalent aliphatic hydrocarbon group having 1 to 10, preferably 1 to 
5, carbon atoms. 
W.sup.1 is a hydrogen atom, 
##STR13## 
in which each of R.sup.1, R.sup.2 and R.sup.3 is a monovalent aliphatic 
hydrocarbon group having 1 to 10, preferably 1 to 5, carbon atoms, a 
monovalent alicyclic hydrocarbon group having 4 to 8, preferably 5 to 6, 
carbon atoms or a monovalent aromatic hydrocarbon group having 6 to 15, 
preferably 6 to 12, carbon atoms. 
m is an integer of 4 to 12, preferably 5 to 10. 
n is an integer of 1 to 100, preferably 3 to 60, particularly preferably 4 
to 50. 
Z is a single bond or a divalent aliphatic hydrocarbon group having 1 to 
10, preferably 1 to 5, carbon atoms. 
W.sup.2 is a hydrogen atom, a monovalent aliphatic hydrocarbon group having 
1 to 10, preferably 1 to 5, carbon atoms, an alicyclic hydrocarbon group 
having 4 to 8, preferably 5 to 6, carbon atoms or a monovalent aromatic 
hydrocarbon group having 6 to 15, preferably 6 to 12, carbon atoms. 
The substituted phenol compounds of the above formulae (II-a) and (II-b) 
may be produced by any methods, while they can be advantageously produced 
by the following methods. 
The substituted phenol compound of the above formula (II-a) can be produced 
by a method in which a hydroxyaralkyl alcohol which has or does not have a 
substituent (X) 
##STR14## 
in which X, p and Y are as defined in the formula (II)] and a lactone 
##STR15## 
in which m is as defined in the formula (II)] are mixed in a proper mixing 
ratio and the mixture is heated in the presence of a catalyst. When the 
mixture is heated, the reaction between the alcoholic hydroxyl group of 
the hydroxyaralkyl alcohol and the lactone and the ring-opening 
polymerization of the lactone proceed at the same time. The polymerization 
degree [corresponding to n in the formula (II)] of the lactone can be 
adjusted as required by adjusting the molar ratio of the hydroxyaralkyl 
alcohol and lactone. When the polymerization degree of the lactone is too 
large, the reactivity of the phenolic hydroxyl group decreases. The 
polymerization degree (n) of the lactone is hence 100 or less, preferably 
60 or less. 
The above catalyst used for the production of the substituted phenol 
compound of the formula (II-a) is selected from organometallic compounds 
of metals such as lithium, sodium, potassium, aluminum, magnesium, 
beryllium, zinc, cadmium and boron and Lewis acids. The amount of the 
catalyst based on the total amount of the lactone is generally 0.001 to 
10% by weight, preferably 0.01 to 3% by weight. 
The reaction between the above substituted or nonsubstituted hydroxyaralkyl

[III] Modified aromatic polyester carbonate resin and method for the 
production thereof 
According to the present invention, further, there is provided a modified 
aromatic polyester carbonate resin containing at least one substituted 
phenyloxy group of the formula (I) in an amount of at least 5 mol % of the 
total amount of terminals, 
##STR16## 
wherein X, p and Q are as defined above. 
The above modified aromatic polyester carbonate resin of the present 
invention can be obtained by adding a substituted phenol compound of the 
above formula (II) to raw materials in the ordinary production of an 
aromatic polyester carbonate resin. 
In the modified aromatic polyester carbonate resin of the present 
invention, the amount of the substituted phenyloxy group of the formula 
(I) based on the total amount of terminals is at least 5 mol %, preferably 
7 to 90 mol %. 
The terminals other than the substituted phenyloxy group of the formula (I) 
are not specially limited, while the remaining terminals may be residues 
derived from the monofunctional phenol compound of the above formula (IV). 
Concerning the amount ratio of the ester bond and carbonate bond which 
constitute the modified aromatic polyester carbonate resin, the ester 
bond:carbonate bond ratio (molar ratio) is 5:95 to 75:25, preferably 10:90 
to 50:50. Further, for retaining the properties of a molded article, the 
specific viscosity of the modified aromatic polyester carbonate resin is 
0.229 to 0.539, preferably 0.246 to 0.451. 
The modified aromatic polyester carbonate resin of the present invention 
can be produced by a method in which a dihydric phenol, one of an aromatic 
dicarboxylic acid and an ester-forming derivative thereof, and a carbonate 
precursor are allowed to react. Specifically, the modified aromatic 
polyester carbonate resin can be produced by a method in which phosgene is 
reacted with a dihydric phenol and one of an aromatic dicarboxylic acid 
and an acid chloride thereof or a method in which diphenyl carbonate is 
reacted with a dihydric phenol and one of an aromatic dicarboxylic acid 
and an ester thereof. 
The reaction of the dihydric phenol, one of an aromatic dicarboxylic acid 
and an acid chloride thereof and phosgene is generally carried out in the 
presence of an acid scavenger and a solvent. The acid scavenger is 
selected, for example, from alkali metal hydroxides such as sodium 
hydroxide and potassium hydroxide and pyridine. The solvent is selected, 
for example, from halogenated hydrocarbons such as methylene chloride and 
chlorobenzene. For the promotion of the reaction, a catalyst such as a 
tertiary amine or quaternary ammonium salt may be used. The reaction 
temperature is generally between 0.degree. and 40.degree. C., the reaction 
time is several minutes to five hours, and the pH during the reaction is 
generally preferably maintained at at least 10. In particular, in the 
method using a dicarboxylic acid in which an ester carbonate anhydride is 
formed as an intermediate, the pH is adjusted to 7 to 9 in the reaction in 
which this ester carbonate anhydride is formed, and the pH is adjusted to 
8 to 10 in the reaction in which the ester carbonate anhydride is 
decarboxylated. 
In the method (ester exchange method) in which a dihydric alcohol, one of 
an aromatic dicarboxylic acid and an ester thereof and diphenyl carbonate 
are allowed to react, these components are mixed in an inert gas 
atmosphere and then allowed to react under reduced pressure generally at a 
temperature between 120.degree. and 350.degree. C. The vacuum degree is 
increased stepwise, and finally decreased to 1 mmHg or less to remove 
phenols formed out of the reaction system. The reaction time is generally 
approximately 1 to 4 hours. A catalyst and an antioxidant may be added as 
required. 
During the polymerization for the synthesis of the above aromatic polyester 
carbonate resin, a predetermined amount of the above Substituted phenol 
compound of the formula (II) can be added. 
The above dihydric phenol used for the production of the modified aromatic 
polyester carbonate resin can be selected from those dihydric phenols 
described with regard to the modified aromatic polycarbonate resin and the 
process for the production thereof, and those dihydric phenols which were 
described as preferred ones are also preferred in this case. 
Examples of the aromatic dicarboxylic acid used for the production of the 
modified aromatic polyester carbonate resin include terephthalic acid, 
isophthalic acid, 5-tert-butylisophthalic acid, 4,4'-diphenyl ether 
dicarboxylic acid, 4,4'-benzophenonedicarboxylic acid, 
4,4'-diphenylsulfonedicarboxylic acid, 2,2-bis(4-carboxylphenyl)propane, 
naphthalenedicarboxylic acid and trimethyl-3-phenylindane-4,5-dicarboxylic 
acid. Of these, terephthalic acid and isophthalic acid are particularly 
preferred. Examples of the ester-forming derivatives of these dicarboxylic 
acid includes acid chlorides and alkyl esters. 
Examples of the carbonate precursor include phosgene, phosgene dimer, 
phosgene trimer, diphenyl carbonate, bischloroformates of the above 
dihydric phenols, di-p-tolylcarbonate, phenyl-p-tolylcarbonate, 
di-p-chlorophenylcarbonate and dinaphthylcarbonate. Of these, phosgene and 
diphenylcarbonate are preferred. 
The modified aromatic polyester carbonate resin of the present invention 
can be molded by any one of an injection molding method, a compression 
molding method, an extrusion molding method and a solution casting method. 
The modified aromatic polyester carbonate resin of the present invention 
may contain additives such as a heat stabilizer, an antioxidant, a light 
stabilizer, a colorant, an antistatic agent, a lubricant and a mold 
release agent and inorganic fillers such as a glass fiber, glass beads, a 
carbon fiber, a metal fiber, talc and silica. Further, it may be used as a 
blend with other thermoplastic resins such as an aromatic polycarbonate 
resin. 
The modified aromatic polyester carbonate resin according to the present 
invention has remarkably improved melt fluidity while it retains its the 
excellent transparency, heat resistance and mechanical properties. It is 
very useful in the fields of structural materials and functional materials 
for electric and electronic parts and optical parts such as an optical 
disk, an optical lens, a liquid crystal panel, an optical card, sheet, 
film an optical fiber, a connector, a vapor-deposited reflection mirror, a 
display and an OPC binder.

According to the present invention, there is provided a modified 
polyarylate resin containing at least one substituted phenyloxy group of 
the formula (I) in an amount of at least 5 mol % of the total amount of 
terminals, 
##STR17## 
wherein X, p and Q are as defined above. 
The above modified polyarylate resin of the present invention can be 
obtained by adding a substituted phenol compound of the above formula (II) 
to raw materials in the ordinary production of a polyarylate resin. 
In the modified polyarylate resin of the present invention, the amount of 
the substituted phenyloxy group of the formula (I) based on the total 
amount of terminals is at least 5 mol %, preferably 7 to 90 mol %. 
The terminals other than the substituted phenyloxy group of the formula (I) 
are not specially limited, while the remaining terminals may be residues 
derived from the monofunctional phenol compound of the above formula (IV). 
The modified polyarylate resin of the present invention can be obtained by 
a method in which the substituted phenol compound of the above formula 
(II) is added to the raw materials in the production thereof. Further, it 
can be also produced by a method used for general polyarylate resins. That 
is, it can be obtained by allowing the dihydric phenol and an aromatic 
dicarboxylic acid chloride to react. This reaction for the production of 
the polyarylate resin is generally carried out in the presence of an acid 
scavenger and a solvent. The acid scavenger is selected, for example, from 
alkali metal hydroxides such as sodium hydroxide and potassium hydroxide 
and pyridine. The solvent is selected, for example, from halogenated 
hydrocarbons such as methylene chloride and chlorobenzene. Further, a 
catalyst may be used for the promotion of the reaction, and the catalyst 
is selected from tertiary amines and quaternary ammonium. The reaction 
temperature is generally between 0.degree. and 40.degree. C., and the 
reaction time is several minutes to 5 hours. During the reaction, 
preferably, the pH is generally maintained at least 10. 
The above dihydric phenol used for the production of the modified 
polyarylate resin can be selected from those dihydric phenols described 
with regard to the modified aromatic polycarbonate resin and the process 
for the production thereof, and those dihydric phenols which were 
described as preferred ones are also preferred in this case. 
Examples of the aromatic dicarboxylic acid dichloride used for the 
production of the modified polyarylate resin include dichlorides of 
terephthalic acid, isophthalic acid, 5-tert-butylisophthalic acid, 
3,4-benzophenonedicarboxylic acid, 4,4'-diphenyl ether dicarboxylic acid, 
3,3'-diphenyldicarboxylic acid, 4,4'-diphenyldicarboxylic acid, 
2,2-bis(4-carboxylphenyl)propane, naphthalenedicarboxylic acid and 
trimethyl-3-phenylindane-4,5-dicarboxylic acid. Of these, dichlorides of 
terephthalic acid and isophthalic acid are particularly preferred. 
The modified polyarylate resin can be obtained by the polymerization of the 
above dihydric phenol, the aromatic dicarboxylic acid dichloride and a 
predetermined amount of the substituted phenol compound of the formula 
(II). In this case, the monofunctional phenol compound of the formula (IV) 
may be added. Further, the same post treatment as that described with 
regard to the modified aromatic polycarbonate resin can be carried out to 
obtain the modified polyarylate having the intended terminal group. 
The modified polyarylate resin of the present invention can be molded by 
any one of an injection molding method, a compression molding method, an 
extrusion molding method and a solution casting method. The modified 
aromatic polyester carbonate resin of the present invention may contain 
additives such as a heat stabilizer, an antioxidant, a light stabilizer, a 
colorant, an antistatic agent, a lubricant and a mold release agent and 
inorganic fillers such as a glass fiber, glass beads, a carbon fiber, a 
metal fiber, talc and silica. Further, it may be used as a blend with 
other thermoplastic resin such as a polycarbonate resin. 
The modified polyarylate resin according to the present invention has 
remarkably improved melt fluidity while it retains its excellent 
transparency, heat resistance and mechanical properties. It is very useful 
in the fields of structural materials and functional materials for 
electric and electronic parts and optical parts such as an optical disk, 
an optical lens, a liquid crystal panel, an optical card, sheet, film, an 
optical fiber, a connector, a vapor-deposited reflection mirror, a display 
and an OPC binder. 
[IV] Low-polymerization degree modified aromatic polycarbonate resin and 
use thereof: 
According to the present invention, further, there is provided an aromatic 
polycarbonate resin having a low polymerization degree, having a specific 
viscosity of less than 0.165 and containing at least one substituted 
phenyloxy group of the formula (I) in an amount of at least 5 mol % of the 
total amount of terminals, 
##STR18## 
wherein X, p and q are as defined above. 
The above aromatic polycarbonate resin having a low polymerization degree 
(to be abbreviated as "low polymer" hereinafter) has no morphological 
retainability per se and cannot be used as a raw material for a molded 
article. However, it can be used as a modifier for improving the melt 
fluidity of a thermoplastic resin, particularly an engineering plastic. In 
particular, the low polymer has an effect on the improvement of an 
aromatic polycarbonate resin in melt fluidity when incorporated in a 
predetermined amount. The low polymer properly has a specific viscosity of 
0.105 to 0.164. The amount of the substituted phenyloxy group of the 
formula (I) in the low polymer is at least 5 mol %, preferably 7 to 90 mol 
%, of the total amount of terminals. The remaining terminals other than 
the substituted phenyloxy group of the formula (I) are not specially 
limited. However, the remaining terminals can have terminal groups derived 
from the monofunctional phenol compound of the formula (IV). 
In principle, the above low polymer can be produced from the same raw 
materials by the same method as those explained with regard to the 
production of the modified aromatic polycarbonate resin. For preventing 
the increase of the polymerization degree, the reaction conditions and the 
amount of the monofunctional phenol compound [including the substituted 
phenol compound of the formula (II)] can be properly selected. 
The above low polymer can be blended with thermoplastic engineering 
plastics having poor moldability such as polycarbonate, polysulfone and 
polyarylate, and the blend can be molded by any one of an injection 
molding method, a compression molding method, an extrusion method and a 
solution casting method. When the low polymer is used as a composition of 
the low polymer and a thermoplastic resin, the composition may further 
contain adding additives such as a heat stabilizer, an antioxidant, a 
light stabilizer, a colorant, an antistatic agent, a lubricant and a mold 
release agent and inorganic fillers such as a glass fiber, glass beads, a 
carbon fiber, a metal fiber, talc and silica.
