摘要：
The present invention is directed to copolymers, which are polymerization products of: (i) a monomer having alpha-olefinic functionality; (ii) a monomer different from (i) having active hydrogen functionality; and (iii) a monomer different from (ii) having acrylic functionality. The molar ratio of the monomer (i) having alpha-olefinic functionality to the monomer (iii) having acrylic functionality is less than 1:1, and the conversion of the monomer (i) having alpha-olefinic functionality during polymerization is greater than 90%. When monomers having methacrylic functionality are used to prepare the copolymer, the molar ratio of the monomer (iii) having acrylic functionality to the monomers having methacrylic functionality is greater than 2:1. Also disclosed are curable film-forming compositions comprising the copolymers.
