Patent ID: 8404786

Claim:
A process for producing a polymer, comprising mixing (A) a polysiloxane compound and (B) a polycarbosilane compound in the presence of a catalyst, water, and an organic solvent, and heating the mixture: wherein the polycarbosilane compound (B) is a polycarbosilane compound having a structure of the following general formula (1), wherein, R 8 represents a group selected from the group consisting of a hydrogen atom, a halogen atom, a hydroxyl group, an alkoxy group, an acyloxyl group, a sulfone group, a methanesulfone group, a trifluoromethanesulfone group, an alkyl group, an alkenyl group, and an aryl group, R 9 represents a group selected from the group consisting of a halogen atom, a hydroxyl group, an alkoxy group, an acyloxyl group, a sulfone group, a methanesulfone group, a trifluoromethanesulfone group, an alkyl group, an alkenyl group, and an aryl group, R 10 and R 11 individually represent groups selected from the group consisting of a halogen atom, a hydroxyl group, an alkoxy group, an acyloxyl group, a sulfone group, a methanesulfone group, a trifluoromethanesulfone group, an alkyl group having 2 to 6 carbon atoms, an alkenyl group, and an aryl group, R 12 to R 14 individually represent a substituted or unsubstituted methylene group, a substituted or unsubstituted alkylene group, a substituted or unsubstituted alkenylene group, or a substituted or unsubstituted arylene group, and x, y, and z individually represent integers from 0 to 10,000 which satisfy “5<x+y+z<10,000”, provided that, when “x=0”, one of R 9 , R 10 , and R 11 is a hydrogen atom, a hydroxyl group, an alkoxy group, an acyloxyl group, a sulfone group, a methanesulfone group, or a trifluoromethanesulfone group, and wherein the polycarbosilane compound (B) additionally contains at least one of the following structural units (5) to (7): wherein R 15 to R 18 individually represents a group selected from the group consisting of a hydrogen atom, a halogen atom, a hydroxyl group, an alkoxy group, an acyloxyl group, a sulfone group, a methanesulfone group, and a trifluoromethanesulfone group, whereby polysiloxane compound (A) and polycarbosilane compound (B) are hydrolyzed and condensed, thereby forming said polymer.
