Vernetzte Diolefinblockpolymerisate, welche funktionelle Epoxygruppen enthalten, Verfahren zu ihrer Herstellung, Klebstoffzusammensetzungen und Ausgangsblockkopolymer

摘要

A cross-linked adhesive composition is provided comprising an epoxidized diene block polymer wherein the polymer is cross-linked through at least some of the epoxy functionality. A process to prepare this polymer is also provided. The preferred polymer is partially hydrogenated and lightly epoxidized. Furthermore, there is provided a viscous block copolymer from which said epoxidized diene block polymer has been derived.
