Abstract
Gels useful as low gloss additives for blends of addition polymers, such as ABS resins, with polycarbonates are prepared by a melt blending operation in which a polyepoxide such as 3,4-epoxycyclohexyl 3,4-epoxycyclohexanecarboxylate is blended with at least one addition polymer such as a styrene-acrylonitrile copolymer, and concurrently with at least one aromatic polycarbonate in at least two increments. The first increment comprises about 20-60% of total polycarbonate and the second increment is subsequently introduced.
