定义
Polyurethane-70 is a complex polymer that is formed by a multi-step synthesis. First, a mixture of polyester diols (a copolymer of Adipic Acid and 1,4-Butanediol; and a copolymer of Adipic Acid and Hexanediol; and Neopentyl Glycol and 1,4-Butanediol are reacted with Isophorone Diisocyanate and hexamethylene diisocyanate (HDI). The resulting urethane polymer is reacted with the sodium salt of N-(2-aminoethyl)-3-aminoethanesulfonic acid, ethylene diamine, and Diethanolamine.
