摘要： Biobased diisocyanates are derived from 3-petadecyl phenol, which is derived from Cardanol harvested from cashew nutshell liquid food waste. The biobased diisocyanates are of the formulas: wherein R is an alkyl chain C15H31 (n-pentadecyl); R1═CH3 or COCH3; and R2 is an alkylene of from about 1 to 18 carbon atoms.

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.-

摘要： 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.
