Polymer with urethane or thiourethane units for use, in particular, as an adhesion primer for bonding metal to rubber

Abstract

A polymer has urethane or thiourethane units, which can be used, in particular, as an adhesion primer for the adhesive bonding of metal or glass to rubber. The polymer comprises base units comprising at least a sub-unit of formula X1CO—NH—, in which X1 respectively represents O or S, and additional units comprising at least a secondary alcohol function and a thioether function in the α position relative to the alcohol function. The polymer can be used as an adhesion primer for the adhesive bonding of a substrate, for example glass or metal, to an unsaturated rubber, or as a corrosion-resistant protective coating for a metal substrate. A metal reinforcer, such as wire, cord, film or plate, can be coated with the polymer.
