摘要： A polyurethane elastomer memory foam composition includes an organic diisocyanate, a chain extender, a crosslinker, a plasticizer, a surfactant, a foaming agent, and a polyester resin, the polyester resin being a random copolymer having randomly distributed subunits of formula 1:




where: R is ethylene, octylene, or decylene; a is from about 1 to about 99 mole % of the polyester resin; b is from about 1 to about 99 mole % of the polyester resin; c is from 0 to about 10 mole % of the polyester resin; and a+b+c=100 mole % of the polyester resin.
