Reactions of poly (vinyl chloride) with magnesium were made to occur under various conditions, but poly (vinyl chloride) did not react with magnesium.The reactions of poly (vinyl chloride) with benzylmagnesium chloride and allylmagnesium chloride as Grignard reagents were carried out in tetrahydrofuran at reflux temperature. It was found that the chlorine atom in the poly (vinyl chloride) was substituted with benzyl and allyl groups by the coupling reaction and that a small amount of Grignard reagent of poly (vinyl chloride) was formed by the magnesium-halogen exchange reaction. The extent of substitution increased with an increase of the reaction period and concentration of the Grignard reagent.The polymers thus obtained became soft with an increase of the extent of substitution.
