摘要： A method for the production of polyurethane elastomers by reacting an isocyanate epolymer having an isocyanate content of from 5 to 10% by weight which is the reaction product of an excessive amount of a polyisocyanate containing at least 85% by weight of 4,4'-diphenylmethane diisocyanate or a variant thereof and a polyether polyol having an average nominal hydroxyl functionality of from 2 to 4, an average hydroxyl equivalent weight of from 500 to 3000, and an oxyethylene content of from 50 to 85% by weight, with an aqueous latex to form a foam, and compressing said foam.
