Abstract
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.

A polyurethane elastomer memory foam composition comprising an organic diisocyanate, a chain extender, a polyurethane 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:
- each R is independently selected from the group consisting of ethylene, octylene, and 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 about 0.1 to about 10 mole % of the polyester resin, and
- a+b+c=100 mole % of the polyester resin,
- wherein the polyurethane crosslinker provides crosslinking of the resulting polyurethane elastomer.
