    摘要： A process is provided for producing improved color acrylonitrile polymer gels involving compounding a composition of an acrylonitrile polymer with an electrophilic reagent to produce acrylonitrile polymer gels, and admixing water with the gels to reduce the yellowness thereof. Improved color, reduced gloss polycarbonate/graft polymer blends are provided by compounding the resultant gels with polycarbonate, a styrene-acrylonitrile copolymer and ABS graft polymer to form reduced gloss PC/ABS/SAN composition. The process provides acrylonitrile gels and reduced gloss compositions exhibiting improved levels of color. The blend compositions are useful as molding resins and the gelled acrylonitrile polymer is useful as a gloss reducing additive.

    摘要： Reduced gloss polycarbonate graft polymer blends are provided by a process which involves compounding styrene-acrylonitrile copolymer in the presence of an electrophilic reagent and preferably an acid to form gels, and then compounding the resultant gels with polycarbonate, a styrene-acrylonitrile copolymer and ABS graft polymer to form reduced gloss PC/ABS/SAN composition. The process limits side reactions during gel formation by preparing the gels first and then compounding the gels with the other resin materials. The blends are useful as molding resins and the gelled acrylonitrile polymer is useful as a gloss reducing additive.
