The method of the present invention provides for the manufacturing of an alkenyl group-containing organopolysiloxane using an alkali catalyst in the presence of oxygen and in the absence of carbon dioxide. The copolymer is characterized by a viscosity of at least 500 cst at 25°C, can be efficiently manufactured and is free of gelation. In the method an organopolysiloxane represented by the average formula R1aSiO(4-a)/2 in which R1 is a monovalent hydrocarbon group free of aliphatic unsaturation and an 4-8 carbon atom alkenyl group-containing organopolysiloxane represented by the average formula R2bR3CSiO(4-b-c)/2 are copolymerized.
