Notes:
The polymers containing units of 1,1,3,3-tetraphenylbut-1-ene [unit (I)] and/or units of 3-methyl-1,1,3-triphenylindan [unit (II)] in the main chain were prepared by acid-catalyzed dimerization of 1,1-diphenylethylene applied to its bifunctional derivatives, for example bis[p-(1-phenylvinyl)phenyl]methane. The structure of yielded polymers depended on catalyst, solvent, temperature, and the molar ratio between the catalyst and the monomer. The molecular weight of polymer having unit (I) was determined by the equilibrium existing between 1,1-diphenylethylene moiety and unit (I). It was shown clearly by gel permeation chromatography that the molecular weight of polymer having unit (II) grew further after the equilibrium mentioned above had been accomplished. The mechanism of the polymerization is discussed.
