A URETHANE-MODIFIED ISOCYANATE COMPOSITION AND POLYURETHANE PRODUCT THEREFROM

摘要

The present invention relates to an isocyanate-terminated composition having utility in the preparation of hydrophilic polyurethanes. The isocyanate composition has an isocyanate content of less than about 15 weight percent a nd comprises the reaction product of an aliphatic or aromatic polyisocyanate, o r mixtures thereof; with a polyol composition that contains a polyether polyol derived from a molecule containing tertiary nitrogen.
