    摘要： A plastic pipe based on polyolefins is provided, which pipe, compared with single-layer pipes of polyolefins, has improved barrier action against (petro)chemical materials, in particular against methanol-containing fuels. This is achieved by a multilayer plastic pipe which comprises the following layers: I. at least one layer based on a polyolefin, II. at least one layer based on a thermoplastic polyester, bonded via III. a layer between them of a suitable coupling agent which contains reactive groups, with adjacent layers being cohesively bonded to one another. The invention makes it possible to obtain plastic pipes having the desired improved property profile.
