Process for producing silicon containing polymers having comb-shape structure.

摘要

A silicon-containing polymer having comb-shape structure comprising a unit of an organopolysiloxane as the main chain and a vinyl polymer as the side chain of the following formula: <CHEM> wherein R<1> is C1-4 alkylene, R<2>, R<3> and R<4> are each C1-4 alky, R is H or methyl, X<1> is hydroxycarbonyl, C2-5 alkoxycarbonyl, C3-8 cycloalkyl-oxycarbonyl or phenyl, n is 1-100,000, R<5> is C1-4 alkyl or phenyl, X<2> is H, C1-4 alkyl, phenyl, chlorine, C1-4 alkoxysilyl, or C1-4 alkyl which is substituted by -NH2, -NH-, -SH or -CN, @ is 1-20, m is 0 or 1-10, which has excellent migration property and is useful as agents for giving water-repellency, adhesion, surface activity, etc. in paints or other compositions, and an intermediate macromonomer, and process for the production thereof.
