| 摘要 |
A rubber-modified thermoplastic polyblend is composed of styrene and acrylonitrile-contg. polymer matrix, 2 and more elastic polymer mixt. dispersed by 2-40 wt.% (where 1 and more of first elastic polymer contains styrene acrylonitrile-grafted EPDM terpolymer rubber). Where second elastic polymer is C1-8 alkyl acrylate rubber-grafted crosslinked homopolymer, grafted substance contains styrene, acrylonitrile, wt. ratio of grafted EPDM rubber: grafted acrylonitrile is 10:90 - 90:10.
