Abstract: Multilayer tubes including an inner layer and a tie layer are described. The inner layer includes a fluorinated polymer, and has an inner surface defining an inner diameter of the multilayer tube and an outer surface separated from the inner surface by a thickness of the inner layer. The tie layer includes a functionalized styrene block copolymer and is disposed on the outer surface of the inner layer. When the multilayer tube further includes an outer layer, the multilayer tubes exhibit improved peel strength as compared to multilayer tubes including the inner layer and outer layer alone. Methods of manufacturing the multilayer tubes and articles comprising the multilayer tubes are also described.
