ABSTRACT:
This invention provides a method of bonding substantially non-fluorinated polymeric material to dissimilar polymers, particularly fluoropolymer materials, utilizing a bonding composition comprising substantially non-fluorinated polymeric material comprising a blend of carboxyl, anhydride, imide, or oxycarboxy functional polyolefin with a suitable organic or inorganic base and an organo-onium compound that is stable in the presence of the base. Multi-layer articles and composite constructions, including retroreflective sheeting, fuel line hoses, and adhesive articles made of a fluoropolymer layer and a substantially non-fluorinated layer are also provided.
