Patent

CA 2326937

This invention relates to novel liquid, ultra-high molecular weight polyurethane plasticizers which contain less than 5% of urethane groups, and to a process for the preparation of these polyurethane plasticizers. These comprise the reaction product of an organic isocyanate component selected from the group consisting of monoisocyanates, diisocyanates, polyisocyanates and mixtures thereof; with an isocyanate-reactive compound having a molecular weight of more than about 4,000, an OH number of 7 to 56 and a functionality of about 1 to about 4. This invention also relates to a process for the production of a polyurethane comprising reacting a polyisocyanate with an isocyanate-reactive compound in the presence of the liquid, ultra-high molecular weight polyurethane plasticizers described herein, and to the resultant polyurethanes containing these plasticizers.
