Abstract
Procedure for the polymerization of suspension of vinyl chloride in an aqueous medium or a mixture of monomers containing vinyl chloride as the main component in the presence of a suspending agent and a polymerization catalyst, in a container equipped with means for stirring and means for separating polymerization heat, comprising a cooling jacket arranged around the container and a reflux condenser connected to the container by a passage, with stirring and maintaining substantially in its thermal conditions separating polymerization heat, characterized in that an opening and closing means is provided mechanic in the passage keeping the passage closed in the initial polymerization stage, because the polymerization heat is separated by means of the cooling jacket, opening the passage only after a conversion of at least 5% has been reached and because starts auxiliary cooling via condenser c hen the passage is open.
