Abstract

Polyurethanes are prepared by reacting a hydroxyl group-containing block copolymer of ethylene and 1:2 propylene oxides having an oxyethylene content of from 0.1 to 7% by weight of the copolymer with a polyisocyanate containing more than two isocyanate groups per molecule, said polyisocyanate being either (a) a product obtained by reacting tolylene di-isocyanate with less than a stoichiometric equivalent of at least one polyol having a M.W. not exceeding 1000 or (b) a composition comprising a major proportion of a diarylmethane diisocyanate and from 5-50% by weight of a polyisocyanate of functionality greater than 2. The polyol used for the preparation of the polyisocyanate (a) may be a polyether, polyester or polyesteramide. In the case of dihydroxy compounds, high temperatures are employed to assist the formation of allophanate groups necessary to form the polyisocyanates having more than two isocyanate groups per molecule. In Example 1 (A) a block copolymer derived from 1:2 propylene oxide, ethylene oxide and glycerol was reacted with a crude diphenylmethane diisocyanate composition containing some triisocyanate in the presence of stannous octoate, water, triethylene diamine and surfactant. In Example (2) the polyisocyanate used was prepared by reacting 4.5 equivalents of tolylene diisocyanate with the polyester derived from trimethylolpropane, pentaerythritol and adipic acid. The polyisocyanate was then reacted with a polyether as in Example (1).
