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.
