Vinyl chloride resin composition with multi-stage impact modifier |
摘要 |
As an impact modifier copolymer to be blended with a vinyl chloride resin, a multilayer copolymer comprising a hard core polymer containing a relatively small quantity of a conjugated diene, a rubbery inner layer polymer containing a relatively large quantity of a conjugated diene, and an outer layer polymer comprising, for example, a copolymer of styrene and methyl methacrylate which is compatible with a vinyl chloride resin is used, whereby a vinyl chloride resin composition well balanced between impact strength and anti-stress-whitening property can be obtained.
