Functional polymers. 63. emulsion copolymerization of maleimide type monomers with acrylonitrile and styrene in ABS latexes

摘要

Copolymerization of maleimide-type monomers: N-phenylmaleimide, N- (2,6-dimethylphenyl) -maleimide and maleimidebound 2 (2-hydroxyphenyl) 2H-benzotriazole with acrylonitrile and styrene was successfully carried out in the presence of acrylonitrile-butadiene or styrene-butadiene latexes. A new type of polymerizable 2(2-hydroxyphenyl)-2H-benzotriazole UV stabilizer with a reactive maleimide group was prepared and gave modi-acrylonitrile-butadience-styrene (ABA) resins with improved thermomechanical properties and increased resistance to ultraviolet radiation.
