Abstract:
A polymer composition comprising (A) a polymer having a silicon atom bound to a hydrolytic group and/or a hydroxyl group, and which is obtained in the presence of a polymerization initiator having a recurring unit represented by the following general formula (2): wherein m is from 5 to 250, and nâ€² is from 4 to 40; and (B) at least one component selected from the group consisting of an organosilane represented by the following general formula (1), a hydrolyzate of the organosilane and a condensate of the organosilane:(R1)nSi(X)4-nâ€ƒâ€ƒ(1) wherein, R1, which maybe the same or different when two or more R1 groups are present, represents a monovalent organic group having 1 to 8 carbon atoms; X represents a halogen atom or an alkoxyl or acetoxyl group having 1 to 8 carbon atoms; and n is an integer of 0 to 2; in which the maximum size of particles contained in said composition is 2 &mgr;m, and the number of particles having a size of 0.2 &mgr;m to 2 &mgr;m in said composition is 1,000 particles/ml or less.
