The α-methylstyrene cyclic dimer,liner dimer~trimer,pentamer~octamer, and 2,4-diphenyl-4-methyl-amylene-(1) were synthesized from α-methylstyrene(α-MS) with activated clay or strong acidic cation exchange resin as catalyst.With strong acidic cation exchange resin as catalyst,the reaction temperature was 140℃,the quantity of catalyst was 0.05 times as much as the amount of α-MS,and the reaction time was 4 h,the yield of α-MS cyclic dimer was 87.2%.The structure of the products was determined by IR,MS and NMR.
