【摘要】 以偶氮二异丁腈(AIBN)为引发剂,研究了β-蒎烯(PI)与苯乙烯(St)自由基共聚反应的动力学,探讨了引发剂浓度、单体浓度、反应温度对聚合速率(RP)的影响。结果表明,聚合速率随着引发剂浓度、苯乙烯浓度的增加而增大,随着β-蒎烯浓度的增加而降低。并得出了该聚合反应的速率方程和表观活化能。更多还原

【Abstract】 The kinetics of copolymerization of free radical reaction of β-pinene with styrene using AIBN as initiator was studied. The effects of the concentration of A1BN, β-pinene, styrene, and polymerization temperature on polymerization rate were investigated. The results showed that the polymerization rate increased with the increasing concentration of initiator and styrene, and decreased with the increasing concentration of β-pinene. Apparent activation energy of copolymerization and polymerization rate equation of this system were obtained.更多还原
