Abstract
A method for increasing the adhesion of a first layer comprising fluoropolymer to a second layer comprising a hydrocarbon polymer is disclosed. The method comprises coating an aliphatic di- or polyamine of less than 1,000 molecular weight onto at least one of the layers. The resulting multi-layer compositions and articles comprising the composition are also disclosed.
