| Abstract: | Synthesis of fiber-grade thermoplastic polyurethane using polyester polyol(PEA), diisocyanate (MDI) and chain extender (1,4-butanediol) as raw material was carried out. The factors including molecular weight of PEA, hard segment content, reaction temperature, moisture content of raw material and so on was studied. Acceptable recipe and technical parameters were gained. |
