二元金属氧化物在30℃下阳离子聚合α-甲基苯乙烯，主要产物为低聚物，特别是二聚体和三聚体。这些二聚体[Y。Kawakami et al., chemistry。列托人。， 13(1980)]和三聚体进行了分离鉴定。在研究了水和吡啶作为中毒碱对二聚体和三聚体的催化活性、产物分布和异构体分布的影响的基础上，提出了一种反应方案。似乎至少有两种不同的活性位点分别产生烯烃低聚物和含单环低聚物。
The cationic polymerization of α-methylstyrene by binary metal oxides at 30°C gave oligomers, especially dimers and trimers, as major products. These dimers [Y. Kawakami et al., Chem. Lett., 13 (1980)] and trimers were separated and identified. A reaction scheme has been proposed on the basis of a study of the effects of water, and pyridine as a poisoning base on catalytic activity, product distribution, and isomer distribution of the dimers and trimers. It seems that there are at least two different active sites which give olefin oligomers and indan ring containing oligomers, respectively.
