  • BIOBASED POLYURETHANE ELASTOMER MEMORY FOAM COMPOSITIONS
    Publication number: 20230265236
    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.

  • Biobased aqueous polyurethane dispersions
    Patent number: 11530332
    Abstract: An aqueous polyurethane dispersion includes particles of polyurethane in water, wherein the polyurethane is derived from an organic diisocyanate, a hydrophilic monomer, a neutralizer, a chain extender, 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 40 to about 100 mole % of the polyester resin, b is from 0 to about 30 mole % of the polyester resin, c is from 0 to about 30 mole % of the polyester resin, and a+b+c=100 mole % of the polyester resin.

  • Polyurethane elastomer compositions, and processes thereof
    Patent number: 10934384
    Abstract: A polyurethane elastomer composition of (a) an organic diisocyanate, (b) a polyester resin; (c) a chain extender comprised of a polyhydric alcohol, (d) a crosslinker, (e) a plasticizer, (f) a surfactant, (g) a blowing or foaming agent, and (h) an optional dye; and where the elastomer has, for example, a hardness value of, for example, from about 20 Asker C to about 60 Asker C, a tensile strength of, for example, from about 1 MPa to about 10 MPa, a resilience of, for example, from about 30 percent to about 60 percent, an elongation at break of from about 150 percent to about 700 percent, and a tear strength of, for example, from about 2 Newtons/millimeters2 to about 4 Newtons/millimeters2.
