| 摘 要： | 用HPLC、DSC、IR和UV等方法对α-蒎烯和苯乙烯的共聚产物进行表征。结果表明α-蒎烯与苯乙烯两种单体确实能进触聚合反应。随着体系中苯乙烯含量的增加,共聚产物的分子量和软化点增加。含少量α-蒎烯的共聚物由于刚性链α-蒎烯的存在使其软化点显著高于苯乙烯均聚物。

Cationic Copolymerization of α-Pinene——Ⅱ. Studies of Copolymer of α-Pinene and Styrene |
| |
| Abstract: | The HPLC, DSC, IR and UV measurements have been used for the characterization of products of α-pinene and styrene copolymerization. The results show that the copolymerization of the monomers does happen and a copolymer of α-pinene and styrene is formed at the study conditions. With increasing ratio of styrene in the system, the molecular weight of copolymer increases. The products containing a small amount of α-pinene have obviously higher softening points than the styrene homopolymer because of the existence of the rigid α-pinene chain. |
