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.

L'invention concerne des compositions de liaison polymères possédant plus d'environ 1 milliéquivalent d'amine primaire/100 grammes de polymère, de préférence plus d'environ 3 milliéquivalents d'amine non tertiaire/100 grammes de polymère. De préférence, le polymère n'est pas significativement réticulé. Ces compositions de liaison peuvent être spécialement utiles pour la liaison de fluoropolymères. L'invention concerne également des procédés de fabrication de ces nouveaux polymères ainsi que d'articles liés multicouches résultants. Ces polymères comprennent des unités ZNHLSi(OP)a(X)3-a-b(Y)b à liaison polymère. Les compositions de liaison de cette invention peuvent être utilisées pour fabriquer des laminés polymères multicouches tels que des tuyaux, des films et des contenants.
