or copolycarbonates--including blends thereof with other 
polycarbonates--of at least about 5,000, and more preferably a number 
average molecular weight of from about 10,000 to about 50,000.

wherein A represents a polyamide (polyamic acid) structural unit of the 
polyetheramide-imide, B represents a polyimide structural unit of the 
polyetheramide-imide, wherein the polymer mole fraction p represents a 
number equal to or greater than zero, preferably a number less than about 
0.5. 
The A and B units of formula IV comprise, respectively, units of the 
following formulas: 
##STR5## 
the O--W--O units of the polyamide or polyimide units can be in the 3 or 
3' or 4 or 4' positions, e.g., in the 3,3'-, 3,4'-, 4,3'- or the 
4,4'-positions, and W is a member of the class consisting of (1) 
##STR6## 
and (2) divalent organic radicals of the general formula 
##STR7## 
where V is a member selected from the class consisting of divalent 
radicals of the formulas 
##STR8## 
where q is 0 or 1, y is a whole number from 1 to 5, the divalent bonds of 
the --O--W--O-- radical being situated on phthalic anhydride-derived 
units, and R.sup.2 is a divalent organic radical selected from the class

atoms and halogenated derivatives thereof, (b) alkylene radicals and 
cycloalkylene radicals having from 2-20 carbon atoms, C.sub.(2-8) alkylene 
terminated polydiorganosiloxane, and (c) divalent radicals included by the 
formula 
##STR9## 
where Q is a member selected from the class consisting of 
##STR10## 
and x is a whole number from 1 to 5 inclusive. 
As used herein and in the appended claims, the polyetheramide-imide 
compositions employed in the invention can have any degree of amidization 
or imidization, which is generally determined by their methods of 
preparation well-known to those skilled in the art. Generally useful 
polyetheramide-imide compositions have an intrinsic viscosity [.eta.] 
greater than about 0.15 deciliters per gram, preferably from about 0.20 to 
about 0.35 deciliters per gram, or even higher as measured in N-methyl 
pyrrolidone (0.1 N in lithium bromide) at 25.degree. C. 
In general, the above-described polyetheramide-imides can be obtained by 
any of the methods well-known to those skilled in the art including the 
reaction of any aromatic bis(ether anhydride)s of the formula 
##STR11## 
where W is as defined hereinbefore with any diamino compound of the 
formula: 
EQU H.sub.2 N--R.sup.2 --NH.sub.2, (VIII) 
where R.sup.2 is as defined hereinbefore. Suitable methods include, in 
general, solution polymerization reactions that are advantageously carried 
out employing well-known solvents, e.g. tetrahydrofuran, 
o-dichlorobenzene/toluene mixtures, m-cresol/toluene mixtures, N-methyl 
pyrrolidone, dioxane/o-dichlorobenzene/toluene mixtures, 
N,N-dimethylformamide, etc., in which to effect interaction between the 
dianhydrides and the diamines at temperatures of from about 25.degree. to 
about 60.degree. C. Alternatively, the polyetheramide-imides can be 
prepared by melt polymerization of any dianhydride of Formula VII with any 
diamino compound of Formula VIII the ingredients at elevated temperatures 
with concurrent intermixing. Generally, melt polymerization temperatures 
between about 180.degree. to about 350.degree. C. preferably about 
185.degree. to about 300.degree. C., and more preferably from about 
190.degree.-210.degree. C. are employed. Any order of addition of chain 
stoppers ordinarily used in melt polymerization can be employed. The 
conditions of the reaction and the proportions of ingredients can be 
varied widely depending on the desired molecular weight, intrinsic 
viscosity, and solvent resistance. In general, equimolar amounts of 
diamine and dianhydride are employed, however, it is essential that a 
slight molar excess (about 1 to 10 mol percent) of an aliphatic or 
aromatic dianhydride be employed in order to effect the production of 
polyetheramide-imides having terminal anhydride groups. 
Included among the many well-known methods of making polyetheramide-imides 
that can be employed in the practice of this invention are those disclosed 
in Heath et al. U.S. Pat. No. 3,847,867, Williams U.S. Pat. No. 3,847,869,

and 3,855,178, etc. These disclosures are incorporated herein in their 
entirety by reference for the purpose of teaching, by way of illustration, 
general and specific methods for preparing polyetheramide-imides suited to 
the practice of this invention.

Blends of halobisphenolethylene polycarbonates and polyetheramide-imide, as 
described hereinbefore, can be prepared by any means known to those 
skilled in the art. Preferred blends are prepared by heating admixtures of 
a halobisphenolethylene polycarbonates and polyetheramide-imide to a 
temperature above their softening point(s). Preferably, the mixing or 
blending is carried out--when carried out in the absence of a solvent--at 
the aforesaid elevated temperature, i.e. above their softening point(s), 
while subjecting the admixture to mechanical working. Accordingly, blends 
can be mixed with such equipment as extruders including mono- and multiple 
screw types, internal Banbury mixers, roll mills, or any other mechanical 
equipment which will subject the admixture to shear stresses at elevated 
temperatures. 
In general, the halobisphenolethylene polycarbonate-polyetheramide-imide 
compositions of this invention can contain other ingredients such as 
reinforcing and nonreinforcing fillers, mold release agents, ultraviolet 
light stabilizers, antioxidants, drip retarding agents, surfactant agents, 
etc. 
The halobisphenolethylene polycarbonates and polyetheramide-imide are 
combinable with each other in all proportions. Consequently, compositions 
comprising from 1 to 99%, by weight, halobisphenolethylene polycarbonate 
and from 99 to 1%, by weight, polyetheramide-imide are included within the 
scope of the invention. By controlling the proportions of 
halobisphenolethylene polycarbonate and polyetheramide-imide formulations 
having predetermined properties which are improved over those of either a 
halobisphenolethylene polycarbonate or a polyetheramide-imide alone are 
readily obtained. In general, blends of halobisphenolethylene 
polycarbonate and polyetheramide-imide have substantially enhanced flame 
retardancy values wherein nominal amounts 1 to 50%, by weight, of 
polyetheramide-imide are combined with 99 to 50%, by weight, of 
halobisphenolethylene polycarbonates, while still retaining or improving 
substantially the physical and chemical polymer property profile 
associated with the polyetheramide-imide component of the blends.

The following examples illustrate--but do not limit--the best method of 
practicing the invention. Unless otherwise indicated in the examples, the 
following general procedures were employed in the preparation and testing 
of the halobisphenolethylene polycarbonate-polyetheramide-imide blends. 
Deviations from the general procedure are noted in the specific examples. 
GENERAL PROCEDURE 
A series of blends of chlorobisphenolethylene polycarbonates and 
polyetheramide-imide were prepared from noncommercially available 
materials. The chlorobisphenol polycarbonate (abbreviated in the examples 
as bisphenol-E polycarbonate) was prepared by the reaction of an aqueous 
alkaline solution of 1,1-dichloro-2,2-bis(4-hydroxyphenyl)ethylene 
(prepared as described hereafter) with phosgene carried out in the 
presence of triethylamine and methylene chloride at a temperature range of 
from about 20.degree. to about 40.degree. C. to form high molecular weight 
chlorobisphenolethylene polycarbonates having an intrinsic viscosity as 
measured in methylene chloride at a temperature of 25.3.degree. C. within 
the range of from about 0.41 to 0.54. 
The 1,1-dichloro-2,2-bis(4-hydroxyphenyl)ethylene employed was prepared in 
accordance with the following detailed description: Under nitrogen, 
methanol (16.2 liters) was charged to a 10 gallon stainless steel reactor. 
Flake KOH (4098 gm., 85% solids, 62.1 moles) was added over 20 minutes 
with cooling to keep the temperature below 45.degree. C. After cooling to 
17.degree. C., 1,1,1-trichloro-2,2-bis-(4-hydroxyphenylethane) (3804 l 
gm., 12 moles) was added as a powder. The stirred reaction mixture was 
then held at 27.degree.-30.degree. C. for 5 days (resulting in a starting 
material level of 3%) and then heated to reflux (75.degree. C.) for two 
hours to lower the starting material level to several hundred ppm. After 
cooling to 25.degree. C. the material was transferred under nitrogen to 
two 22 liter glass flasks and acidified to a pH of 5 with concentrated HCl 
(4320 ml.). The material was then split into two equal halves. One of the 
halfs was then heated to near reflux and 7.5 liters of water at 75.degree. 
C. was added. The resulting mixture was cooled to 25.degree. C. over 3 
hours and the resulting reaction product crystals were collected in a 
basket centrifuge and washed with 12 liters of water to dissolve and 
remove KCl which had also crystallized from the mother-liquor. The 
resulting product was redissolved in 4 liters of methanol, filtered 
through a 0.2 micron millipore filter, heated to 75.degree. C. and 4 
liters of hot water were added. After cooling, the crystals were collected 
in a basket centrifuge, washed with 4 liters of water, and dried in a 
vacuum oven at 100.degree. C. to afford 150 gm., and 89% yield of product, 
i.e. 1,1-dichloro-2,2-bis(4-hydroxyphenyl)ethylene. Liquid chromotography 
analysis indicated less than 150 ppm. starting material. Product nitrogen 
content was less than 5 ppm. and iron was less than 0.5 ppm. 
The polyetheramide-imide--characterized by dianhydride and diamino 
reactants--having an intrinsic viscosity [.eta.] of 0.2-0.6 dl./gm. at 
25.degree. C. as measured in chloroform or N-methyl-pyrrolidone (NMP) 
depending upon the degree of imidization, and a glass-transition 
temperature T.sub.g of 140.degree.-225.degree. C. was prepared in 
accordance with the procedures described in U.S. Pat. No. 3,850,885 which 
procedures are incorporated herein by reference in their entirety. 
The resulting bisphenol-E polycarbonate and polyetheramide-imide were 
powder blended into a series of compositions, extruded and chopped into 
pellets. The pelleted materials were injected or compression molded and 
tested accordingly: 
Notched Izod Impact (1/i" specimens, ft.-lb. per inch of notch) ASTM D256 
method A; 
Oxygen Index ASTM D2863; 
Tensile Yield Stress (psi) ASTM D1822; L specimen, 0.05"/min.; 
Flexural Strength (psi) ASTM D790.
