The polypropylene glycol polyurethane modified by polyhexylene carbonate diol (HPPU)was synthesized from polyhexylene carbonate diol(PHCD),polypropylene glycol (PPG),4,4'-diphenylmethane diisocyanate(MDI)and 1,4-butylene diol(BDO)by one-step technique.
以聚己撑碳酸酯二醇(PHCD)和聚丙二醇(PPG)、4,4′-二苯基甲烷二异氰酸酯(MDI)和1,4-丁二醇(BDO)为原料,经一步法合成了聚己撑碳酸酯二醇改性的聚丙二醇醚型热塑性聚氨酯(HPPU)。
