IMPACT STRENGTH MODIFIED POLYCARBONATE COMPOSITIONS

摘要

The present invention relates to compositions comprising: A) 10 - 99 weight percent aromatic polycarbonate and/or aromatic polyester carbonate, B) 1 - 35 weight percent rubberized graft copolymer of B.1 5 to 95 of at least one vinyl monomer and B.2 95 to 5 of one or more graft foundations having a glass transition temperature of < 10° C, C) 0 - 40 weight percent vinyl(co)polymer and/or polyalkylene terephthalate, excepting a copolymer made of a-methyl-styrene and acrylnitrile, D) 0 - 50 weight percent phosphorous flame retardant, relative to the sum of components A+B+C, E) 0 - 50 weight percent of additives, relative to the sum of components A+B+C, characterized in that component B can be obtained by reacting component B.1 and the graft foundation B.2 by means of emulsion polymerization, wherein an emulsifier according to formula (I) is used, said compositions being characterized by a high resistance to hydrolysis. The invention further relates to the use of polycarbonate compositions for producing molds and molded parts.
