The polymerization of poly(vinyl chloride) (PVC), head-to-head macroradical plays an essential role in the formation of branches and the appearance of interruption processes that lead to labile unsaturated end groups. A reaction mechanism is suggested to explain these processes and the method of ...
When PVC is prepared by polymerization at a low concentration of monomer, it also has a detectable number of internal double bonds. In poly(vinyl chloride-co-carbon monoxide), the carbon monoxide is contained in chlorocarbonyl branches. These branches are formed by the addition of monomer to -...
