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。
The copolymerization products of α-pinene and styrene were characterized by HPLC, DSC, IR and UV. The results show that α-pinene and styrene monomer can indeed come into contact with the polymerization reaction. As the styrene content in the system increases, the molecular weight and softening point of the copolymer increase. The copolymer containing a small amount of α-pinene has a softening point significantly higher than that of a styrene homopolymer due to the presence of the rigid chain α-pinene.
