Abstract:
1. An impact-modified acrylic alloy composition comprising: a) 100 parts of an impact-modified acrylic resin composition containing 15 to 95 weight percent acrylic polymer and 85 to 5 weight percent of one or more core/shell impact modifiers having a core layer and one or more shell layers with a Tg of greater than 0° C., and one or more elastomeric intermediate layers having a Tg of less than 0° C., b) 5 to 150 parts of one or more low melt viscosity polymers that are compatible with the acrylic polymer, wherein said low melt viscosity polymers have a melt flow rate of more than 10 g/10 minutes as measured by ASTM D1238at 230° C./10.4 kg of force, and wherein the low melt viscosity polymer comprises at least one polymer selected from the group consisting of poly(ethylene glycol), poly(propylene gycol), poly(vinyl acetate), poly(vinyl alcohol), poly(vinyl chloride), maleic anhydride-strene-vinyl acetate copolymers, ethylene-vinyl acetate copolymers, styrene-acrylonitrile copolymers, olefin-(meth)acrylate copolymers, olefin-(meth)acrylate-maleic anhydride copolymers, cellulose acetate, cellulose triacetate, cellulose propionate, cellulose acetate propionate, cellulose acetate butyrate, and cellulose acetate phthalate; wherein the weight percent of impact modifier in the alloy composition is from 5 to 60 weight percent.
