| Abstract: | Chloropolyether terminated polybutadiene(CTPB) was synthesized with hydroxyl terminated polybutadiene(HTPB) as initiator and boron-trifluoride etherate as catalyst by cationic ring-opening polymerization of epichlorohydrin.Epoxy terminated polybutadiene(ETPB) with epoxy value of 0.0549 was synthesized by ring-closing reaction of CTPB under basic conditions.The effects of NaOH/CTPB molar ratio,reaction temperature and reaction time on ring-closing reaction were discussed.Curing procedures of different curing... |
