## 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 fluropolymers. 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.

## Claims

### Claim 1

A multilayer bonded article comprising a bonding composition bonded to a second polymer, wherein the bonding composition comprises the reaction product of an amino substituted organosilane ester or ester equivalent and a first polymer that has a plurality of polar functionalities combinatively reactive with the silane ester or ester equivalent to displace the ester or ester equivalent groups, wherein the first polymer is covalently bonded to the silane via the silicon atom; and wherein the second polymer is selected from the group consisting of THV, HTE, PVDF, ETFE and combinations thereof.
