ABSTRACT:
A substantially linear poly-vinylarene/polyurethane block copolymer prepared by reacting (1) a difunctional poly-vinylarene which is produced by anionic polymerization and which contains isocyanate-reactive groups, (2) a diisocyanate or an isocyanate prepolymer, and (3) a diol having a high molecular weight or a chain extender having a lower molecular weight, is disclosed to be suitable for the preparation of shaped articles, coatings, coupling agents and compatibilizers.
