Abstract:
1. A thermoplastic molding composition, comprising A) from 10 to 99.99% by weight of a polyamide; B) from 0.01 to 20% by weight of a high-functionality hyperbranched polyetherol with an OH number of from 3 to 1350 mg KOH/g of polyetherol (to DIN 53240, part 2) wherein the degree of branching of the hyperbranched polyetherol is from 10 to 99.9%; and C) from 0 to 70% by weight of further additives, where the total of the percentages by weight of components A) to C) is not more than 100%; wherein component B) is obtained via reaction of at least one tri- or polyhydric alcohol and of further dihydric alcohols, and also optionally of further monohydric alcohols and/or modifier reagents, with the aid of acidic catalysts, where no glycerol is used as trihydric alcohol.
