Abstract
Polyalkylindanes of the type described in earlier communications__S. H. Weber, D. B. Spoelstra__ and Ernest H. Polak, Rec. trav. chim. 74, 1179 (1955).
S. H. Weber, J. Stofberg, D. B. Spoelstra and R. J. C. Kleipool, ibid. 75, 1433 (1956).
may also be prepared by condensation of styrenes and alkenes under the influence of suitable catalystsThis new synthesis of polyalkylindanes is the subject of French Patent, 1, 109, 699 of Oct. 10, 1954, assigned to Polak's Frutal Works Inc., others pending.
