Abstract
Polymer bonding compositions having greater than about 1 milliequivalent primary amine/100 grams of the polymer, more preferably greater than about 3 milliequivalent non-tertiary amine/100 grams of the polymer. Preferably the polymer is not significantly crosslinked. These bonding compositions may be especially useful for bonding fluoropolymers. Processes for making the novel polymers and the resulting multilayer bonded articles are described. The polymers include polymer-bonded ZNHLSi(OP)a(X)3−a−b(Y)b units. The bonding composition may be used for making multi-layer polymer laminates such as tubes and films and containers.
