Soluble acrylic copolymers have been widely used in many applications. Copolymers in solid state with significant advantages, such as convenience for delivery and storage, high active content, are of importance in industries. They have been paid more and more attention in recent years. So it is significant to study soluble acrylic copolymers in solid state and their properties. In the paper, soluble acrylic copolymers were synthesized by instant polymerization and inverse suspension polymerization (ISP). Th...
