Platinum-vinylsiloxane catalysts for hydrosilation. Cpds. have formula (I) Where R = halogen-substituted or unsubstituted monovalent hydrocarbon radical; c = 1,2,3; d = 0,1,2; e = 0,1,2,3; x = 1-100; y = 0-198 and (x + y) = 1-199; f=0.67-67, but f / x = 0.67. These compds. are prepared by reacting a platinum halide pref. a chloride and a vinylsiloxane but the prod. has subst. no chem bound halogen and contains 0.5-46% chem bound Pt. |
