Polyurethane-74 is a copolymer formed by reacting Isophorone Diisocyanate (q.v.) with neopenyl glycol mono(hydroxypivalate) and a polyester pre-polymer that is made by condensing diethyl carbonate, Hexanediol, Glycol, and epsilon-caprolactone. The polymer is capped with 2-hydroxyethyl acrylate.

Polyurethane-75 is a copolymer made by reacting toluene diisocyanate, Bisphenol A Bis-(2-Hydroxypropyl) Ether, and poly(1,4-butanediol)-28 and then capping the resulting copolymer with 2-hydroxypropyl methacrylate.

Polyurethane-81 is a urethane polymer formed by a multi-step reaction. First, a hydroxyl-terminated polyester made by condensing hexamethylene carbonate with Epsilon-Caprolactone. The polyester is then reacted with Isophorone Diisocyanate and Neopentyl Glycol, then capped with 2-ethylhexanol.

Polyurethane-82/HDI Crosspolymer is Polyurethane-82 that has been crosslinked with 1,6-Hexamethylene Diisocyanate.

Cyclohexanol, 4,4′-(1-methylethylidene)bis-, polymer with .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, 2-hydroxypropyl methacrylate-blocked

1,3-Dioxolan-2-one, polymer with 1,6-hexanediol, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane and 1,5-pentanediol, 2-hydroxyethyl acrylate-blocked
