SUSPENSION COPOLYMERIZATION OF ACRYLONITRILE WITH ACRYLICACID ALKYL ESTER

摘要

PURPOSE:To prepare a pearl-like copolymer of a specific range of acrylonitrile content by suspension polymerization of a monomer mixture consisting of acrylonitrile and acrylic acid alkyl ester in a system containing an organic dispersant, specific surfactant and stannous or zinc compound to effect preventing blocking the polymer produced during the polymerization process.
