SILICON-CONTAINING POLYMER, METHOD OF MANUFACTURING THEREOF, AND CURABLE POLYMER COMPOSITION

摘要

A silicon-containing polymer represented by the following average unit formula: (O2/2SiR1-R2-C6H4-R2-SiR1O2/2)x [R3 SiO(4-a)/2]y(R4O1/2)z (wherein R1 designates identical or different, substituted or unsubstituted monovalent hydrocarbon groups; R2 designates identical or different, substituted or unsubstituted alkylene groups; R3 designates substituted or unsubstituted monovalent hydrocarbon groups; R4 designates alkyl groups or hydrogen atoms; 'a' is a positive number that satisfies the following condition: 0 = a = 3; and 'x', 'y', and 'z' are positive numbers that satisfy the following conditions: 0 x 0.1; 0 y 1; 0 = z 0.1; and (x + y + z) = 1); and a curable polymer composition comprising: (A) the aforementioned silicon-containing polymer; (B) an organosilicon compound that contains in one molecule at least two silicon-bonded hydrogen atoms; and (C) a hydrosilylation catalyst.
