摘要: 有机过氧化物对铁芳烃引发阳离子光聚合有敏化作用。敏化作用大小与过氧化物的氧化性和浓度大小一致:过氧化苯甲酰(BPO)>过氧化二碳酸二(α-苯氧乙基)酯(BPPD)>过氧化异丙苯(DCP).过氧化物可促进芳烃铁阳离子与环氧化物的络合及环氧化物的开环聚合,能降低聚合反应温度和提高聚合反应速度,但过氧化物的用量及光的强度不宜过高。

Abstract: The promotion of organic peroxides on photopolymerization of epoxy resin was examined using iron arene complex as initiators. The activity was dependent upon the oxidability and concentration of the peroxide and it decreases in the order of: benzoyl peroxide(BPO)>bis(α-phenoxyethyl) peroxydicarbonate(BPPD)>dicumyl peroxide(DCP). By promoting the complexation of iron arene cation with epoxides and the ring opening of epoxides,the peroxides could decrease the polymerizing temperature and increase the polymerization rate. However,overdose of the peroxides and too high intensity of light were undesirable.

Key words: epoxy resin, iron arene complex, organic peroxide, cationic photopolymerization
