Abstract
A silicon-containing polymer which is represented by general formula (5) below and has a weight-average molecular weight in the range from 500 to 500,000: (In the formula, Ais an organic group of 2-10 carbons, having a carbon-carbon unsaturated group; Ris an alkylene group of 1-20 carbons, a bivalent aromatic group of 6-20 carbons, or a bivalent alicyclic group of 3-20 carbons; n is 0 or 1; Ris a hydrogen atom or an alkyl group of 1-10 carbons (Rin one molecule may be the same type or a combination of two or more different types.); each of x and y is a positive number; each of w and z is 0 or a positive number; 0≦z/(w+x+y)≦2; and 0.01≦y/(w+x)≦5), and the heat-resistant resin composition comprising the silicon-containing polymer.
