Aliphatic Polyester-Acrylic Blend Molding Composition Having Good Ductility and Weatherability |
摘要 |
A molding composition has a bulk resin component formed from: a) 5 to 93 percent by weight of cycloaliphatic polyester resin such as poly(1,4-cyclohexane-dimethanol-1,4-dicarboxylate having a melt viscosity of at least 6000 poise; b) 5 to 93 percent by weight of an acrylate polymer or co-polymer; and c) 2 to 30 percent by weight of an impact modifier with a a shell comprising a repeating units derived from a C1-12 alkyl(meth)acrylate and a rubbery core having weatherability properties. The composition may further include a polycarbonate polymer or a styrene-acrylonitrile polymer as a phase compatabilizer as well as other conventional additives such as pigments, mineral fillers, antioxidants and the like. The composition has improved ductility, impact strength and weatherability.
