The high solubility in the usual solvents makes the chlorinated PVC most suitable for laquers, adhesives and fibres. For this reason, the radiation-induced solution chlorination of PVC in methylene chloride was studied. The results of many experiments show that during the reaction between chlorine and PVC the solvent (methylene chloride) is chlorinated only in a small percentage to chloroform (9.5 % ) and finally to tetrachloromethane (0.1 % ). It was found that the radiation-induced chlorinated PVC has the same structure as the thermally chlorinated polymer, while the thermal stability and the rate of degradation of the radiation products show the better data for application purposes.
