Patent ID: 8278381

Claim:
A thermoplastic molding composition, comprising: A) from 10 to 98% by weight of at least one thermoplastic polymer; B) from 0.01 to 20% by weight of B1) at least one hyperbranched polycarbonate with 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 hyperbranched A x B y polyester, or a mixture of thereof, wherein A x and B y are different monomers and indices x and y are the number of functional groups present in A and B, 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 and a COOH number of from 0 to 600 mg KOH/g and wherein component B2) has a glass transition temperature Tg from −50° C. to 140° C., wherein a degree of branching of both B1) and B2) is from 10 to 99.9%, and wherein B1) and B2) have both structural and molecular non-uniformity; C) from 1 to 30% by weight of a flame retardant combination composed of, based on 100% by weight of C), C1) from 20 to 99% by weight of a halogen-containing flame retardant, and C2) from 1 to 80% by weight of an antimony oxide; 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%.
