이 원료는 다단계 반응으로 형성되는 복합폴리머로서 헥산디올, 네오펜틸글라이콜 및 아디픽애씨드의 공중합체가 헥사메칠렌디이소시아네이트와 반응한 후 N-(2-아미노에칠)-3-아미노에탄설포닉애씨드 및 에칠렌디아민과 반응하여 얻은 것이다.

Polyurethane-34 is a complex polymer that is formed in a multi-step reaction. A copolymer of Hexanediol, Neopentyl Glycol, and Adipic Acid is reacted with hexamethylene diisocyanate. The resulting polymer is further reacted with N-(2-aminoethyl)-3-aminoethanesulfonic acid and ethylenediamine: Polyurethane-14 is a copolymer formed from isophorone diisocyanate, dimethylol propionicacid, and 4, 4'-isopropylidenediphenol reacted with propylene oxide, ethylene oxide and PEG/PPG-17/3.

本品は、１，６－ヘキサンジオール、ネオペンチルグリコールとアジピン酸（＊）の共重合体にヘキサメチレンジイソシアネート（ＨＤＩ）を反応させて得たプレポリマーに、更にＮ-(２－アミノエチル）-３-アミノエタンスルホン酸とエチレンジアミンを反応させて得られる高分子である。
