Process for the production of cross-linked graft copolymers |
摘要 |
A process for the production of cross-linked graft copolymers by the radically initiated precipitation copolymerization of an ethylene/vinyl ester copolymer as graft base and a mixture to be grafted of one or more aromatic monovinyl compounds, acrylonitrile and/or methacrylonitrile, a cross-linking agent containing two or more carbon-carbon double bonds, and, optionally, another monoolefinically unsatured copolymerizable monomer wherein the ungrafted base is precipitated by the addition of a precipitating agent simultaneously with the precipitating cross-linked graft copolymer.
