摘要
以异佛尔酮二异氰酸酯(IPDI)、聚氧化丙烯二醇(PPG-220)、二羟甲基丙酸(DMPA)、蓖麻油(CO)等为主要原料,合成交联型水性聚氨酯乳液,在此乳液中加入丙烯酰胺、引发剂(KPS),交联剂(BMA)进行自由基聚合,制备具有IPN结构的聚氨酯-聚丙烯酰胺(PU-PAAm)水凝胶。研究了(PU-PAAm)水凝胶溶胀率(SR)受pH值、温度(T)、交联剂用量等因素的影响。
Crosslinked Aqueous Polyurethane was synthesized mainly with isophorone diisocyanate（IP- D1）,polyoxypropylene propylene-glycol ether （PPG-220）,dimethyopropionic acid （DMPA）and castor oil （CO）. AAM ,BMA ascrosslinking agent and initiator potassium persulfate （KPS） were added to form the IPN waterborne polyurethane-polyacrylamide （PU-PAAm）hydrogels.The swelling ration of the IPN hydrogel （PU-PAAm）, which can act as a influence ofpH,temperature and crosslinking agent, was studied in detail.
