Abstract
A method for increasing the adhesion of a first layer comprising fluoropolymer to a second layer comprising a melt-processable, substantially non-fluorinated polymer is disclosed. The method comprises mixing, preferably in a melt, an aliphatic di- or polyamine of less than 1,000 molecular weight with the melt-processable, substantially non-fluorinated polymer. The resulting multi-layer compositions and articles comprising the composition are also disclosed.
