Method for creating hydroxyfunctional polymers, the isocyanate group terminal polyaddition products which can be gathered from them and their production

摘要

Preparation of polyurethane comprises (a) providing at least a polymer (A) with at least two hydroxyl group, which is obtained by reacting a polymer with at least two carboxyl- and/or phenol groups with at least a compound having at least a glycidyl group; and reacting the polymer with at least a polyisocyanate.
