Abstract

A process for the treatment of the vinyl chloride polymers in which the polymer is subjected to a heat treatment in the presence of an aliphatic alcohol and a metal carboxylate, characterized in that the heat treatment is carried out at a temperature comprised between 135 and 165ºC in the presence of methyl alcohol and at least one aliphatic hydroxycarboxylate of a metal selected from the alkali and alkaline earth metals.
