                 Abstract:  Poly(butyl  fumarate)  (PBF)  was  successfully  synthesized  by  two-step  reaction  with  diethyl
                                                                                                 1
                 fumarate and 1,4-butanediol as basic raw material. The polymers were characterized by FTIR,  HNMR,
                 GPC, TG and DSC. The effects of reaction parameters on the yield of PBF were studied. Based on the
                 polymerization  mechanisms,  the  reaction  time,  temperature  and  doses  of  alcohol  were  investigated  to
                 achieve maximum polymer yield. The results suggested that the appropriate molecular weight (M n=2773)
                 and higher yield (61.94%) of PBF are obtained when the molar ratio of diethyl fumarate and 1,4-butanediol
                 is 1∶3, the reaction temperature is 130  ℃  and the reaction time is 8 h. PBF/N-vinyl-2-pyrrolidone (NVP)
                 composite was prepared by UV-curing and thermo-curing respectively. And the effects of initiator dosage
                 on  crosslinking  and  curing  degree  of  the  composite  were  also  investigated.  The  results  showed  that
                 crosslinking and curing effect of the composite were better, when the dosage of photoinitiator and thermal
                 initiator were 2.5% phenylbis(2,4,6-trimethylbenzoyl) phosphine oxide (BAPO) and 3% benzoyl peroxide
                 (BPO) [0.2% N,N-dimethyl-p-toluidine (DMT)], respectively.
