α-蒎烯共聚链增长初探

Preliminary Study on Chain propagation in the Copolymerization of α-Pinene

研究了AlCls、芳烃络合物作用下α-蒎烯与苯乙烯、α-甲基苯乙烯、β-蒎烯等不同单体的共聚合反应，结果表明，正碳离子连接分散正电行的基团（苯环）或抗衡负离于对正联离子活性中心能起稳定化作用均有利于进行链增长，从而得到较高收率和软化点的共聚产物．

In the presence of AlCl3 or aromatic colllplex, α-Pinene was copoly -merized with different monomers, such as styrene, α-methylstyrene andβ-pinene. Results show that progression of chain can be promoted eitherwhen carbon cation connected with the group that can disperse positivecharge or when counter ion can stabilize the activity center of carboncation. Resin with high yield and softening point was obtained.
