Abstract:
1. A thermoplastic molding composition, comprising; A) from 10 to 98% by weight of at least one thermoplastic polymer; B) from 0.01 to 50% by weight of B1) at least one hyperbranched polycarbonate having an OH number of from 1 to 600 mg KOH/g of polycarbonate wherein component B1) has a glass transition temperature Tg of from −80° C. to 140° C., or B2) at least one a hyperbranched A or a mixture of thereof, wherein A wherein x is at least 1.1 and y is at least 2.1, wherein B2) has an OH number of from 0 to 600 mg KOH/g wherein component B2) has a glass transition temperature Tg of from −50 to 140° C. and a COOH number of from 0 to 600 mg KOH/g, wherein a degree of branching of B2) is from 10 to 99.9%, and wherein B1) and B2) have both structural and molecular non-uniformity; C) from 1 to 40% by weight of a halogen-free flame retardant, selected from the group consisting of phosphorus-containing or nitrogen-containing compounds, the P—N condensates, and mixtures thereof; and D) from 0 to 60% by weight of other additives, wherein the total of the percentages by weight of components A) to D) is 100%.
