摘要： Transparent molding compositions are prepared by blending from 50 to 99 parts by weight of a transparent polyamide, and from 1 to 50 parts by weight of a graft copolymer, such that the sum of the parts by weight of the transparent polyamide and the graft copolymer is 100. The graft copolymer is prepared by reacting from 0.5 to 25% by weight, based on the graft copolymer, of a branched polyamine having at least 4 nitrogen atoms and having a number average molecular weight Mn of at least 146 g/mol, with polyamide-forming monomers selected from the group consisting of lactams, w-aminocarboxylic acids, equimolar combinations of diamine and dicarboxylic acid, and combinations thereof.

摘要： A multilayer plastic pipe having strong bonding between the layers has at least one layer I of a polyolefin molding composition comprising a polyolefin, at least one layer II of a polyester molding composition, and at least one layer III of an adhesion promoter containing reactive groups and located between layers I and II. The polyester molding composition of layer II comprises a polyester and one or more compounds selected from a compound having two or more carbodiimide groups, carboxylic anhydride groups, maleimide groups or oxazine groups.
