The preparation of a homopolymer from 3,3,3-trifluoro-propylmethyldichlorosilane has been accomplished on a small scale. Experimental conditions have been studied for the re action of trichlorosilane and methyldichlorosilane with olefins. For hydrocarbon olefins, the best yield of addition product was obtained at 2500 C without a peroxide catalyst. The use of a platinum catalyst supported on charcoal allows the use of lower reaction temperatures and shorter reaction times in these additions.
