Abstract
A method for the preparation of flexible polyurethane foam by reacting a polyisocyanate containing at least 85% by weigh of 4,4'-diphenylmethane diisocyanate or a liquid variant thereof with a polyol composition comprising at least one poly(oxyethylene-oxyalkylene) polyol, the composition having an average nominal hydroxyl functionality of from 2.5 to 6, a number average hydroxyl equivalent weight of from 1000 to 300 and an average oxyethylene content of from 25 to less than 50% by weight and with water.
