Polymers based on polyarylene siloxanes and freeradical-polymerizable monomers

A polymer obtained by free-radical polymerization of free-radical-polymerizable monomers in the presence of a polysiloxane dissolved in a solvent, where the free-radical-polymerizable monomers used are at least one compound of the formula I, ##STR7## where R.sup.1 and R.sup.2 are, independently of one another, hydrogen, COOH, C.sub.1 -C.sub.18 -alkyl, cyclohexyl, C.sub.1 -C.sub.4 -alkylcyclohexyl, C.sub.6 -C.sub.10 -bicycloalkyl, or C.sub.6 -C.sub.18 -tricycloalkyl,

• R.sup.3 is hydrogen or methyl,
• R.sup.4 is hydrogen, (C.sub.1 -C.sub.20)-alkyl, 2-hydroxypropyl, glycidyl,
• --[CH.sub.2 CH.sub.2 --O].sub.n H, having n=1 to 5,
• --[CH.sub.2 ].sub.m --OH, having m=3 to 18,
• --[CH.sub.2 ].sub.2 O--[CO--(CH.sub.2).sub.5 ].sub.x OH, where x=a number from 1 to 3,
• or
• --[CH.sub.2 CHOHCH.sub.2 ]--O--(CO)R,
• where R is a C.sub.1 to C.sub.18 -alkyl radical and the polysiloxane used is at least one aromatic polyarylene siloxane of the formula III, ##STR8## where R.sup.9 and R.sup.10 are identical or different and are, independently of one another, a C.sub.1 -C.sub.12 -alkyl radical, a C.sub.6 -C.sub.14 -aryl radical, or an unsubstituted or substituted vinyl radical, and
• R.sup.11, R.sup.12, R.sup.13 and R.sup.14 are identical or different and are, independently of one another, hydrogen, a C.sub.1 -C.sub.3 -alkyl radical or a substituted or unsubstituted C.sub.6 -C.sub.14 -aryl radical and
• --X--is a group --C(CH.sub.3).sub.2 --, --C(CF.sub.3).sub.2 --, --S--, --SO.sub.2 --, --CH.sub.2 -- or a cyclohexylidene group which can be unsubstituted or substituted, or is a chemical bond and
• M is equal to 0 or 1 and N is a number from 2 to 500.
