ABSTRACT:
Urethane-filled, polyether polyols are prepared by reacting (1) a hexamethylene diisocyanate residue from the phosgenation of hexamethylene diamine with contains less than 10% by weight monomeric hexamethylene diisocyanate and has a total isocyanate group content of at least 25% with (2) an alcohol containing at least four ether linkages in amounts such that the equivalent ratio of isocyanate groups in (1) to hydroxyl groups in (2) is from about 0.9:1.0 to about 1.0:0.9 and subsequently dissolving this reaction product in a polyether polyol.
