摘要：
A method for purifying 3-methacryloxypropyldimethylhalosilanes or 3-methacryloxypropyl methyldihalosilanes which is characterized by the fact that 1-methyl-2-methacryloxyethyldimethyl halosilanes or 1-methyl-2-methacryloxyethylmethyldihalosilanes contained in products or fractions consisting of 3-methacryloxypropyldimethylhalosilanes or 3-methacryloxypropylmethyl dihalosilanes produced by a hydrosilation reaction of allyl methacrylate with dimethylhalosilanes or methyldihalosilanes are decomposed by means of at least one copper compound selected from the group consisting of copper hydroxides, copper salts other than copper halides, and copper oxides, after which these compounds are subjected to fractional distillation.
