Abstract
The present invention is directed to a multilayer material having in order a layer of fluorinated polymer, a layer of binder for fluorinated polymer having a polymer A with moieties (1)-(4), and a layer of polymer which is incompatible with the fluorinated polymer. The multilayer material is useful for making a pipe which has a superior barrier properties to petroleum products and the additives thereof. The present invention also relates to a pipe having a multilayer structure having two layers of polyamide and a layer of binder comprising a polymer A with glutarimide moieties (1)-(4) in between. The pipe has superior barrier properties to petroleum products and the additives.
