C-5161 FIRE RETARDANT BLEND OF INTERPOLYMER COMPOSITION, CHLORINATED VINYL CHLOR- IDE POLYMER AND VINYL CHLORIDE POLYMER Abstract of the Disclosure Flame retardant blends having good impact resis- tance and a high heat deflection temperature which comprise: (1) an interpolymer comprising: (a) crosslinked (meth)- acrylate; (b) crosslinked styrene-acrylonitrile; and (c) un- crosslinked styrene-acrylonitrile polymeric components; (2) a chlorinated vinyl chloride polymer; and (3) a vinyl chlor- ide polymer. The blends have utility as an outdoor con- struction material for the construction industry, for ex- ample, for residential siding, gutter systems, shutters and the like. The amount of the interpolymer (1) which is pres- ent in the blend predominates over the respective weight amounts of either of the two other components (2) or (3).
