Hydrogenated octasilsesquioxane- vinyl group- containing copolymer and method for manufacture

摘要

A method for manufacturing an organic solvent-soluble hydrogenated octasilsesquioxane-vinyl group-containing compound copolymer comprising reacting 1 mol of(A) a hydrogenated octasilsesquioxane described by formula 1 <CHEM> with 0.2 to less than 3 mol of (B) a divinyl group-containing compound described by formula (2) CH2=CH-L-CH=CH2 where L is selected from the group consisting of (a) a divalent hydrocarbon group comprising 3 to 10 carbon atoms and (b) -(SiR2O)m-SiR2-, where each R is independently selected from the group consisting of alkyls comprising 1 to 6 carbon atoms and aryls comprising 6 to 9 carbon atoms and 1 ≤ m ≤ 10; in the presence of a hydrosilylation catalyst.
