摘要:
Soft polymer mixtures of(a) 10 to 50 parts by weight of a graft polymer obtained from a particulate, highly cross linked diene or alkyl acrylate rubber and graft polymerized alkyl methacylate, acrylonitrile, styrene, alkyl acrylate or mixtures thereof and(b) 90 to 50 parts by weight of a partly cross-linked, particulate, rubber-like copolymer of acrylonitrile and/or methyl methacrylate and C.sub.1 to C.sub.8 alkyl acrylate having a gel content of from 60 to 99% by weight and an average particle diameter (d.sub.50) of from 0.1 to 0.6 .mu.m,and a process for the preparation of the mixtures and their use for the production of moulded articles.
摘要:
This invention relates to soft, rubber-like, thermoplastically processible polymer alloys based on 10 to 50% by weight of (cyclo)aliphatic, thermoplastic polyamides and 90 to 50% by weight of special cross-linked, particulate alkyl acrylate copolymer rubbers suitable for the preparation of rubber-like, elastic moulding compounds.The invention also relates to a process for their preparation.
