ANTI-FOGGING/ANTI-BLOCKING FILMS OF ACRYLIC COPOLYMERS

摘要

ACRYLIC COMPOSITION AND FILM An acrylic composition useful for making films which are nonblocking and free of moisture-fogging tendencies made from acrylic polymers containing 40 to 80 parts of an alkyl acrylate or alkyl methacrylate having an alkyl group containing 2 to 10 carbon atoms and 20 to 60 parts vinyl nitrile by the use of several combinations of compounding agents, the combinations being sorbitan monofatty acid esters and polyoxyethylene monofatty acid esters.
