摘要：
A prepolymer and products made from the preopolymer is described. The prepolymer includes the reaction product of at least one isocyanate and at least one natural oil based polyol. The natural oil based polyol includes at least two natural oil moieties separated by a molecular structure having an average of at least about 19 ether groups between any 2 of the natural oil moieties or by a polyether molecular structure having an equivalent weight of at least about 480.
