Silyl group-containing vinyl resin and curable composition.

摘要

silyl group-containing vinyl resin having a molecular weight of 500 to 100,000, the main chain of which is substantially composed of a vinyl polymer, and which has per one molecule at least one silicon atom to which a hydrolyzable group is bonded, and which has 1 to 95 % by weight of units of a monomer selected from the group consisting of an acrylic acid alkyl ester and a methacrylic acid alkyl ester, said alkyl having not less than 10 carbon atoms, which has an excellent abrasion resistance and scratch resistance, and a curable composition containing the silyl group-containing vinyl resin.
