Resinous composition and sheet product therefrom

摘要

A blended composition consisting of a thermoplastic olefin resin (Comp. A) with an acrylonitrile-styrene-alkyl acrylate copolymer (Comp. B) was attempted to create substitution for vinyl chloride compound prepared from vinyl chloride resin proper and a plasticizer, but resulted in inferior interdispersibility. Incorporation of an epoxy resin (Comp. C) has brought definite improvement in the interdispersibility. A resinous composition including the components A, B, and C has the utility of substitution for vinyl chloride compounds as well as its products. (Comp. C) is selected from the group consisting of epoxidized diene block copolymers including, in their molecules, a block prepared by polymerization from a vinyl aromatic monomer and another block prepared by polymerization from a conjugated diene monomer, wherein remnant diene groups after the polymerization have been epoxidized or further partially hydrogenated.
