BUTYL RUBBER IONOMER-THERMOPLASTIC GRAFT COPOLYMERS AND METHODS FOR PRODUCTION THEREOF

摘要

The present invention is directed to the functionalization of butyl rubber ionomer and optionally the grafting of polyamide to halobutyl rubber ionomers. Specifically, disclosed are methods and products resulting therefrom for creating functionalized ionomers and grafting polyamide to halobutyl ionomers via reactive extrusion. The process comprises reacting a halobutyl polymer with at least one nitrogen and/or phosphorous based nucleophile to provide a halobutyl ionomer comprising conjugated diene units; grafting of an amine-reactive dienophile to said ionomer to form a functionalized ionomer; and optionally blending the resulting functionalized ionomer with polyamide.
