Polymer dispersions in polyester polyols

摘要

Polymer dispersions (I) containing OH-prepolymers (II) obtained by reacting tetrahydrofuran oligomers with less than one mol polyisocyanate. Independent claims are also included for the following: (1) a method for the production of (I) by radical polymerisation of olefinically-unsaturated monomers in presence of (II) and polyester-polyols without unsaturated groups; (2) polymer dispersions (I) obtained by this method; and (3) shoe soles containing the reaction products of (I) with polyisocyanates.
