The invention relates to a thermoplastic molding composition comprising: A) from 69 to 98% by weight, based on components A and B, of a thermoplastic selected from the group consisting of polyvinyl chloride, polystyrene, polymethyl methacrylate, polyamide, polybutylene terephthalate, and polyoxymethylene; B) from 2 to 31% by weight, based on components A and B, of a polymer mixture comprising: i) from 30 to 70% by weight, based on the total weight of components i to ii, of at least one polyester based on aliphatic and/or aromatic dicarboxylic acids and on an aliphatic dihydroxy compound; ii) from 70 to 30% by weight, based on the total weight of components i to ii, of polylactic acid; iii) from 0 to 10% by weight, based on the total weight of components i to iv, of a copolymer which contains epoxy groups and which is based on styrene, acrylate, and/or methacrylate; iv) from 0 to 15% by weight, based on the total weight of components i to iv, of nucleating agents, lubricants and antiblocking agents, waxes, antistatic agents, and defogging agents, or dyes; and C) from 0 to 40% by weight, based on components A to C, of other additional materials.
