摘要： Unsaturated dimers which contain 2,4-diphenyl-4-methyl-1-pentene as their main component (i.e., in an amount of greater than 95%) are produced by reacting an .alpha.-methylstyrene at a temperature of from 20.degree. to 100.degree.C. in the presence of a sulfonic acid type cation-exchange resin catalyst and in the further presence of a primary or secondary monohydric alcohol containing from 2 to 5 carbon atoms. By this reaction, side products including a saturated dimer of 1,1,3-trimethyl-3-phenylindane, trimers and higher polymers are produced only in an extremely small amount. The unsaturated dimers are very useful as a molecular weight modifier when employed, instead of dodecylmercaptans, for the production of polymers such as an ABS resin, an AS resin, and the like.
