Studies on suspension and emulsion. LX. Composite polymer emulsion film with temperature‐sensitive properties

摘要

AbstractThe mechanical and optical properties of film cast from poly(ethyl acrylate)/polystyrene composite emulsion prepared by seeded emulsion polymerization were changed drastically by heat treatment. Such temperature‐sensitive properties can be controlled by regulating the contents and the glass transition temperature of polymer. It was concluded that such a specific phenomenon is due to phase inversion in the heterogeneous structure of the film derived from the particle morphology determined by the polymerization recip
