| titleOfInvention | Polycarbonate compositions with improved resistance to hydrolysis |
| abstract | The invention relates to compositions containing A) 62 to 96 wt.% of at least one polymer selected from the group consisting of linear aromatic polycarbonate and linear aromatic polyester carbonate, B) 1 to 15 wt.% of at least one graft polymer produced by the emulsion polymerization of B.1) 5 to 95 wt.%, based on B, of a mixture of B.1.1) 50 to 99 wt.%, based on B.1, of at least one monomer selected from the group of vinyl aromatics, ring-substituted vinyl aromatics, and acrylic acid-(C1-C8)-alkylester or mixtures of said compounds and B.1.2) 1 to 50 wt.%, based on B.1, of at least one monomer selected from the group of vinyl cyanide, acrylic acid-(C1-C8)-alkylester, unsaturated carboxylic acids, and derivatives of unsaturated carboxylic acids, B.2) 5 to 95 wt.%, based on B, of a rubber-containing graft base containing a diene rubber or a copolymer of a diene rubber with an additional copolymerizable monomer, C) 0 to 5.8 wt.% of a rubber-free vinyl(co)polymer, D) 1 to 20 wt.% of at least one phosphorous-containing flame retardant of the general formula (IV), in which R1, R2, R3, and R4 independently of one another each represents optionally halogenated C1- to C8-alkyl, C5- to C6-cylcoalkyl, each of which is optionally substituted with alkyl, C6- to C20-aryl, or C7- to C12-aralkyl, n independently of one another represents 0 or 1, q represents whole-number values from 1 to 30, X represents a polynuclear aromatic group with 13 to 30 C atoms which can optionally be substituted with halogen and/or alkyl groups, E) 0.8 to 4.0 wt.% of a mineral filler based on talc with a particle size d50 of 0.2 to 10 µm, and F) 0.1 to 20.0 wt.% of at least one polymer additive, wherein the compositions do not contain a graft polymer produced in a bulk polymerization process. The invention also relates the use of the compositions in order to produce molded bodies and to the molded bodies themselves. |
