Bis-HEMA Poly(1,4-Butanediol)-13/1,4-Butanediol/IPDI Copolymer is a urethane polymer formed by the reaction of poly(1,4-butanediol)-13, 1,4-Butanediol, and Isophorone Diisocyanate (IPDI). The polymer is end-capped with HEMA.

Bis-HEMA Poly(1,4-Butanediol)-14/PEG-2/PPG-3/IPDI Copolymer is a copolymer of poly(1,4-butanediol)-14, PEG-2, PPG-3 and Isophorone Diisocyanate (IPDI), end-capped with HEMA.

Bis-HEMA Poly(1,4-Butanediol)-22/DMPA/Neopentyl Glycol/IPDI Copolymer is a urethane polymer formed by the reaction of poly(1,4-butanediol)-22, Dimethylolpropionic Acid, Neopentyl Glycol, and Isophorone Diisocyanate. The polymer is end-capped with HEMA.

Bis-HEMA Poly(1,4-Butanediol)-22/IPDI Copolymer is a copolymer of poly(1,4-butanediol)-22 and isophorone diisocyanate (IPDI) end-capped with hydroxyethyl methacrylate (HEMA)

Bis-HEMA Poly(1,4-Butanediol)-9/SMDI Copolymer is a copolymer of Poly(1,4-Butanediol)-9 and Saturated Methylene Diphenyl Diisocyanate (SMDI) end-capped with HEMA.

Bis-HEMA Poly(Caprolactone Neopentyl Glycol)/1,4 Butanediol/ IPDI Copolymer is a urethane polymer formed by a multi-step process. First, a polyester is made by reacting Epsilon-Caprolactone with Neopentyl Glycol, which is subsequently reacted with 1,4-Butanediol and Isophorone Diisocyanate. The resulting polymer is end-capped with HEMA.

Bis-HEMA Poly(Caprolactone Neopentyl Glycol)/IPDI Copolymer is formed by reacting a pre-polymer of caprolactone and Neopentyl Glycol with Isophorone Diisocyanate (IPDI). The polymer is end-blocked with HEMA

Bis-HEMA Poly(Caprolactone/Pentaerythritol)/IPDI Copolymer is a urethane polymer formed by a multi-step process. First, a polyester is made by reacting Epsilon-Caprolactone with Pentaerythritol, which is subsequently reacted with Isophorone Diisocyanate. The resulting polymer is end-capped with HEMA.

Bis-HEMA Poly(Caprolactone/Pentaerythritol)/IPDI Copolymer Succinate is a urethane polymer formed by a multi-step process. First, a polyester is made by reacting Epsilon-Caprolactone with Pentaerythritol, which is subsequently reacted with Isophorone Diisocyanate. The resulting polymer is end-capped with HEMA and esterified with Succinic Anhydride.
