摘要： A process for the preparation of graft polymers from ethylene homopolymers or copolymers and olefinically unsaturated monomers, especially from ethylene/vinyl ester copolymers, in the presence of a radical forming agent in homogenous or heterogeneous phase, in which a mixture of (meth)acrylonitrile, at least one aromatic vinyl compound and vinylchloride are polymerized in the presence of an ethylene homopolymer or copolymer. The products obtained contain no ungrafted styrene/acrylonitrile copolymer and more than 80% by weight of the graft polymer is chemically almost uniform in structure. The products obtained according to the invention are eminently suitable for use as coating materials and as materials which can be thermoplastically processed.
摘要翻译：一种在乙烯均聚物或共聚物和烯属不饱和单体，特别是乙烯/乙烯基酯共聚物的自由基形成剂存在下在均相或非均相中制备接枝聚合物的方法，其中（甲基）丙烯腈，在乙烯均聚物或共聚物存在下聚合至少一种芳族乙烯基化合物和氯乙烯。获得的产品不含未接枝的苯乙烯/丙烯腈共聚物，并且大于80重量％的接枝聚合物在结构上化学上几乎均匀。根据本发明获得的产品非常适合用作涂料和作为可热塑化处理的材料。
