Abstract
Manufacturing process for homogeneous copolymers of vinyl chloride with a difficult to condense monomer, consisting of copolymerizing the vinyl chloride in the presence of one or more radical-forming catalysts, of a solid substance inert under polymerization conditions at a temperature between 40 and at 80ºC and at a pressure lower than the saturating vapor pressure of the vinyl chloride at the polymerization temperature, characterized in that to obtain homogeneous copolymers, the copolymerization is carried out in a fluidized bed with the aid of a fluidizing gas consisting of a mixture of chloride of vinyl and of the comonomers whose composition remains constant.
