Summary The cationic oligomerization of p-isopropyl-α-methylstyrene by CF3SO3H in dichloromethane has been investigated. The electronic spectrum of the corresponding active species showed two absorption maxima at 362 and 490 nm. The reaction did not give high polymers but rather dimers and trimers as major products, the proportion of olefinic dimers and trimers increasing at lower temperatures compared with the indanic products. Oligomers with ¯Dn ≃ 20 were obtained at −58°C for a monomer to initiator ratio greater than 1800.
