Claim 1
Independent Claim
124 words
THE PROCESS FOR PREPARING A MONOMERIC ORGANOHALOGENOSILANE IN WHICH ALL THE HALOGENS IN THE SAID SILANE ARE ATTACHED DIRECTLY TO THE SILICON ATOM, WHICH PROCESS COMPRISES EFFECTING REACTION IN THE LIQUID PHASE UNDER SUBSTANTIALLY ANHYDROUS CONDITIONS AND UNDER AUTOGENOUS PRESSURE AT A TEMPERATURE OF FROM 0* TO 150*C. IN THE PRESSURE OF A VINYL POLYMERIZATION PEROXY CATALYST FOR THE REACTION BETWEEN (1) AN UNSATURATED HYDROCARBON SELECTED FROM THE CLASS CONSISTING OF UNSATURATED ALIPHATIC HYDROCARBONS AND UNSATURATED CYCLOALIPHATIC HYDROCARBONS HAVING A SINGLE OLEFINE UNSATURATION, AND (2) A SILICON HYDRIDE CONTAINING A HYDROGEN AND A HALOGEN ATTACHED DIRECTLY TO THE SILICON ATOM, THE REMAINING VALENCES OF THE SILICON BEING SATISFIED BY A MEMBER SELECTED FROM THE CLASS CONSISTING OF HYDROGEN, ALKYL RADICALS, ARYL RADICALS, AND HALOGENS.
