  • Weather resistant theromplastic resin composition
    Patent number: 5834558
    Abstract: A styrenic thermoplastic resin composition comprising a mixture of: (A) 50-90 wt % of a styrenic polymer; (B) 5-35 wt % of a chlorinated polyethylene; (C) 5-35 wt % of a modified ethylene-propylenic rubber; and (D) 0-10 wt % of vinyl graft copolymer has superior weather resistance and mechanical properties such as impact strength and tensile properties. The resin composition also provides improved layer peeling tendency which is one of the most troublesome problems in conventional resins such as acrylonitrile-chlorinated polyethylene-styrene resins.
