摘要： A blend of a softer continuous phase polymer reinforced with harder acrylic star polymer particles having reactive functional groups with crosslinking ability built in or provided by a third polymer. The harder polymer has a T.sub.g at least 10.degree. C. above that of the softer polymer, and the acrylic star polymer is preferably made by group transfer polymerization. This blend provides coating compositions, films and bulk polymer with enhanced toughness and flexibility.
