Polyurethane-95 is a urethane polymer made by reacting poly(1,4-butanediol)-28, poly(1,4-butanediol)-41, Hydrogenated Bisphenol A and Isophorone Diisocyanate. The resulting polymer is end-capped with 2-Hydroxyethyl Acrylate.

olyurethane-96 is the urethane polymer formed by reacting a polymeric diol with Isophorone Diisocyanate. The urethane polymer is capped with 2-Hydroxypropyl Acrylate. The polymeric diol is composed of Hexanediol and 1,5-Pentanediol condensed with Ethylene Carbonate.

Polyurethane-97 is formed by the reaction of Dimethyl Carbonate, Hexanediol and Isophorone Diisocyanate. The resulting pre-polymer is capped with a mixture of Hydroxyethyl Acrylamide, hydroxypropyl acrylamide and hydroxybutyl acrylamide.

Polyurethane-98 is a urethane polymer that is made in several steps. First, a polyether diol is made by reacting 1,2-butylene oxide with Propylene Glycol. A second diol polymer is made by condensing Adipic Acid and Isophthalic Acid with 3-methylpentane-1,5-diol. These two polymers are mixed and then reacted with Trimethylhexamethylene Diisocyanate to form a polyurethane. The polyurethane is capped with Hydroxyethyl Acrylamide.
