Abstract
The present invention relates to a thermoplastic molding composition composed of polycarbonate and inorganic fillers which comprises from 0.01 to 0.5 part by weight of at least one anhydride-modified alpha-olefin terpolymer and which has a high degree of rigidity and nevertheless exhibits good strength, as well as stress-strain characteristics corresponding to those of an unreinforced polycarbonate. Surprisingly, the molding composition additionally exhibits an improvement in flame retardancy. The invention relates in particular to flame-retardant, thermoplastic molding compositions filled with glass fibers, and to the production and use thereof. The property profile is, surprisingly, independent of the degree of interaction of the filler with the polycarbonate matrix.

Abstract
The present invention relates to a process for the preparation of polyricinoleic acid ester polyols having primary hydroxyl end groups. It furthermore relates to polyricinoleic acid ester polyols obtainable according to the invention and polyurethane polymers prepared using these polyols. The process comprises the steps: a) polycondensation of ricinoleic acid until a hydroxyl number of >0 mg of KOH/g to <60 mg of KOH/g is reached; and b) reaction of the product obtained in step a) or of a secondary product of the product obtained in step a) comprising carboxyl groups with an epoxide of the general formula (I), wherein R1 represents hydrogen, an alkyl radical or an aryl radical, with the proviso that >80% by weight to <100% by weight, based on the total amount of the epoxide (I) employed, is ethylene oxide and the reaction is carried out in the presence of an amine as the catalyst.

Abstract
Impact-modified polycarbonate compositions are disclosed that comprise a first graft polymer based on silicone-acrylate composite rubber as graft base, wherein the amount of silicone rubber is from 65 to 95 wt. % (based on the graft base), and a second graft polymer containing free copolymer, that is to say copolymer that is not chemically bonded to the rubber, and having a weight-average molecular weight of from 60,000 to 150,000 g/mol. The use of the polycarbonate compositions in the production of molded articles, and to the molded articles themselves are also disclosed. The compositions and molding compositions have an optimum combination of good elongation at tear, good hydrolytic stability and low melt viscosity.
