TECHNICAL FIELD 
The invention relates to organosilicon compounds containing 
oligoisobutylene or polyisobutylene groups, a process for their 
preparation, a process for their equilibration and coating processes using 
these compounds. 
DESCRIPTION OF THE RELATED ART 
Formulations containing polyorganosiloxanes and polyisobutylene are widely 
known. Examples are U.S. Pat. No. 3,855,174 and U.S. Pat. No. 4,725,648. 
It is an object of the invention to provide new organosilicon compounds 
containing bound oligoisobutylene or polyisobutylene groups, which can be 
prepared in a simple process using readily available starting materials; 
which are hydrophobic and resistant to detergents; and which have 
structures which can be built up in a targeted way. No transition metal 
catalyst, e.g. hydrosilylation catalysts, should be used in their 
preparation. The organosilicon compounds of the invention should also be 
able to be made hydrophilic, reactive, or crosslinkable, and should have, 
in particular, excellent properties as polishes. These and other objects 
are achieved by the invention.

3,3,3-trifluoro-n-propyl radical, the 2,2,2,2',2',2'-hexafluoroisopropyl

Preferred organosilicon compounds containing oligoisobutylene or 
polyisobutylene groups are those of the formula 
EQU A.sub.g R.sub.3-g SiO(SiR.sub.2 O).sub.o (SiRAO).sub.m SiR.sub.3-g 
A.sub.g(VI) 
where A and R are as defined above, g is 0.1 or 2, m and o are 0 or an 
integer from 1 to 1000, with the proviso that at least one radical A is 
present per molecule in a terminal or lateral position. The radicals 
(SiR.sub.2 O).sub.o and (SiRAO).sub.m can occur mixed in any order. 
The organosilicon compounds of the invention preferably have an average 
molecular weight of from 500 to 1,000,000 g/mol, preferably from 5000 to 
150,000 g/mol, and preferably have a viscosity of from 10 to 1,000,000 
mm.sup.2.s.sup.-1 at 25.degree. C., preferably from 20 to 100,000 
mm.sup.2.s.sup.-1 at 25.degree. C. 
The organosilicon compounds of the invention can also be wax-like or solid. 
The organosilicon compounds used in the process of the invention are 
preferably those of the formula 
EQU E.sub.g R.sub.3-g SiO(SiR.sub.2 O).sub.o (SiREO).sub.m SiR.sub.3-g 
E.sub.g(VII) 
where R, E, g, o and m are as defined above and (SiR.sub.2 O).sub.o and 
(SiREO).sub.m can occur mixed in any order. 
In the process of the invention, it is possible to use compounds known from 
the literature which catalyze reactions similar to the Michael reaction. 
Examples are glacial acetic acid, tin(IV) chloride, sodium methoxide and 
alkali metal amides, which can be used in amounts of from 0.1 to 2% by 
weight of the total weight of the starting materials. 
Furthermore, free-radical initiators in the reaction of mercaptans, for 
example azo compounds and/or peroxo compounds, can be added as catalysts 
in amounts of 0.1 to 5% by weight. 
In the process of the invention, preference is given to using 0.001-10 mol, 
preferably 0.01-3 mol and particularly preferably 0.1-2 mol, of compound 
of the formula (V) per mol of the radical E in the organosilicon compound 
(IV). 
In the process of the invention, unreacted radicals E in the organosilicon 
compound (IV) can be reacted further with alkoxylated amines or acrylates 
to make the organosilicon compounds of the invention hydrophilic. 
In the process of the invention, it is possible to use organic solvents or 
water or mixtures of the two. Examples of organic solvents are toluene, 
xylene, tetrahydrofuran (THF), n-butyl acetate, isopropanol and 
dimethoxyethane. Organic solvents used are preferably removed after the 
reaction. 
The process of the invention is preferably carried out at the pressure of 
the surrounding atmosphere, i.e. at about 1020 hPa (abs.). However, it can 
also be carried out at higher or lower pressures. Furthermore, the process 
of the invention is preferably carried out at a temperature of from 
25.degree. C. to 150.degree. C., preferably from 25.degree. C. to 
120.degree. C., particularly preferably from 25.degree. C. to 100.degree. 
C. 
The reaction of acrylated organosilicon compounds with monoaminated 
polyisobutylene is preferred. 
If the monoaminated oligoisobutylene or polyisobutylene is used in a 
substoichiometric amount based on the (meth)acrylate groups, the 
organosilicon compounds of the invention can be crosslinked via the 
remaining (meth)acrylate groups by a free-radical mechanism or via a 
hydrosilylation. 
Remaining amine groups can be acylated or neutralized after the reaction. 
The organopolysiloxanes containing oligoisobutylene or polyisobutylene 
groups and obtained by the process of the invention can be equilibrated 
with organopolysiloxanes selected from the group consisting of linear 
organopolysiloxanes having terminal triorganosiloxy groups, linear 
organopolysiloxanes having terminal hydroxyl groups, cyclic 
organopolysiloxanes and copolymers of diorganosiloxane and 
monoorganosiloxane units. 
As linear organopolysiloxanes having terminal triorganosiloxy groups, 
preference is given to using those of the formula 
EQU R.sub.3 SiO(SiR.sub.2 O).sub.r SiR.sub.3, 
where R is as defined above and r is 0 or an integer from 1 to 1500; as 
linear organopolysiloxanes having terminal hydroxyl groups, preference is 
given to using those of the formula 
EQU HO(SiR.sub.2 O).sub.2 H, 
where R is as defined above and s is an integer from 1 to 1500; as cyclic 
organopolysiloxanes, preference is given to using those of the formula 
EQU (R.sub.2 SiO).sub.t, 
where R is as defined above and t is an integer from 3 to 12; and as 
copolymers, preference is given to using those comprising units of the 
formula 
EQU R.sub.2 SiO and RSiO.sub.3/2, 
where R is as defined above. 
The ratios of the organopolysiloxanes and the organopolysiloxanes 
containing oligoisobutylene or polyisobutylene groups used in the 
equilibration which may be carried out are determined only by the desired 
proportion of the oligoisobutylene or polyisobutylene groups in the 
organopolysiloxanes produced in the equilibration which may be carried out 
and by the desired mean chain length. 
In the equilibration which may be carried out, use is made of acidic or 
basic catalysts which promote the equilibration. Examples of acidic 
catalysts are sulfuric acid, phosphoric acid, trifluoromethanesulfonic 
acid, phosphonitrilic chlorides and acidic catalysts which are solid under 
the reaction conditions, for example acidic-activated bleaching earth, 
acidic zeolites, sulfonated coal and sulfonated styrene-divinylbenzene 
copolymers. Preference is given to phosphonitrilic chlorides. 
Phosphonitrilic chlorides are preferably used in amounts of from 5 to 1000 
ppm (parts per million) by weight, in particular from 50 to 200 ppm by 
weight, in each case based on the total weight of the organosilicon 
compounds used. Examples of basic catalysts are benzyltrimethylammonium 
hydroxide, tetramethylammonium hydroxide, alkali metal hydroxides, 
alkaline earth metal hydroxides in methanolic solution, phosphonium 
hydroxides and silanolates. Preference is given to alkali metal hydroxides 
which are used in amounts of from 50 to 10,000 ppm by weight, in 
particular from 500 to 2000 ppm, in each case based on the total weight of 
the organosilicon compounds used. 
The equilibration which may be carried out is preferably carried out at 
from 80.degree. C. to 150.degree. C. and at the pressure of the 
surrounding atmosphere, i.e. at about 1020 hPa (abs.). However, higher or 
lower pressures can also be employed if desired. The equilibration is 
preferably carried out in from 5 to 20% by weight, based on the total 
weight of the organosilicon compounds respectively used, of a 
water-immiscible solvent such as toluene. 
Before the work-up of the mixture obtained in the equilibration, the 
catalyst can be made inactive. 
The novel organosilicon compounds containing oligoisobutylene or 
polyisobutylene groups are simple to prepare and can be made to have a 
targeted degree of hydrophobicity. If the monoaminated polyisobutylenes 
are used in a substoichiometric amount based on the acrylate groups, free 
acrylate groups remain in the silicone oil and these can then be reacted 
with monoaminated polyoxyalkylenes in a second step. 
Varying the ratio of polyisobutylenes to polyoxyalkylenes gives amphiphylic 
block copolymers having a degree of hydrophilicity or hydrophobicity which 
can be set exactly (see Example 6). Apart from the hydrophobicity, the 
copolymers of the invention have a good soft feel and a low tendency to 
yellowing. Furthermore, they are resistant to detergents. 
The above-mentioned organosilicon compounds of the invention are preferably 
used in the treatment of flat textile structures, for example woven 
fabrics, knitteds or nonwovens. The invention further relates to textile 
fiber treatment and leather treatment. Furthermore, the compounds of the 
invention can be used in the cosmetics, household cleaners, polishes, 
surface coatings and building industries. They also serve as 
compatibilizers for organosilicon compounds and organic rubbers. In 
addition, the compounds of the invention serve as additives for hair 
sprays, as thread lubricants, as coatings for woven fabrics and as 
polishes, preferably for stoves.

number of 0.322 mmol of amine/g of solution, and 40 g (0.434 mol) of 
toluene for 4.5 hours. 
After filtration, the reaction mixture is evaporated to constant weight in 
a high vacuum (1 mbar) at 120.degree. C. This gives 67.8 g (97.8% of

having an amine number of 0.322 mol of amine/g of solution, and 20 g 
(0.217 mol) of toluene for 4 hours. 
After filtration, the reaction mixture is evaporated to constant weight in 
a high vacuum (1 mbar) at 120.degree. C. This gives 62.8 g (97.8% of 
theory) of a colorless, clear oil having a viscosity of 38,600 mm.sup.2 /s 
at 25.degree. C. 
EXAMPLE 4 
Example 1 is repeated as described above, except that 43.38 g of KEROKOM 
PIBA (from BASF) are used instead of 86.74 g. This gives 30.77 g (87% of 
theory) of a clear, yellow oil having a viscosity of 4900 mm.sup.2 /s at 
25.degree. C. (Copo 1). 
EXAMPLE 5 
10 g of Copo 1 are admixed with 3% by weight of 2,2'-azoisobutyronitrile 
and heated at 100.degree. C. for 4 hours. This gives a completely 
crosslinked, yellow rubber. 
EXAMPLE 6

20 g (0.217 mol) of toluene for 4 hours. 
After filtration, the reaction mixture is evaporated to constant weight in

and of an end-stopped silicone oil (Comparison 2) built up of 
trimethylsiloxy, dimethylsiloxy and aminoethylaminopropylmethylsiloxy 
units, having a viscosity of 1000 mm.sup.2 /s at 25.degree. C. and lateral 
amine groups (0.58 mmol of amine groups/g) in benzene were applied to a 
lightly soiled decorative glass ceramic plate having dimensions of 25 
cm.times.25 cm and were distributed uniformly. The plate was subsequently 
polished with a moist household cloth until the surface was free of 
streaks. 
At this point, the cleaning action and the handling fastness of the 
protective film were assessed:

Subsequently, the protective action was tested by sprinkling the surface 
with an about 3 mm thick layer of sugar and the plate was heated until the 
sugar had completely caramelized or carbonized. After cooling, the 
adhesion of the caramelized sugar, the ease and completeness of its 
detachment from the surface and also the nature of the surface in respect 
of damage (chipping) were assessed.
