Abstract
A multilayer composition comprising:A) a first layer based on copolymers of ethylene (E) with tetrafluoroethylene (TFE) and/or chorotrifluoroethylene (CTFE);B) a second intermediate layer comprising thermoprocessable copolymers of ethylene (E) with tetrafluoroethylene (TFE) and/or chorotrifluoroethylene (CTFE) modified with acrylic monomers;C) a third layer based on hydrogenated polymers; said multilayer composition containing in layer B) and/or in layer C) one or more crosslinking agents.
