摘要： Process for the manufacture of highly elastic polyurethane foams which comprises reacting (a) a mixture comprising a polyfunctional polyether glycol having a mean molecular weight between about 3,000 and 5,500, water and catalysts with (b) a quasi-prepolymer mixture of polyether polyols enriched with at least two different organic polyisocyanates. Also included is a further process whereby the mixtures are foamed in a mold at about room temperature or slightly higher.
