RADIATION GRAFT COPOLYMERISATION OF POLYVINYL CHLORIDE AND ETHYLENEIMNE

Graft copolymerisation of ethyleneimine monomer on polyvinyl chloride (PVC) fiber was studied. It was found that ethyleneimine could be grafted as well as vinyl monomer by the γ-ray irradiation.Retardation by hydroquinone and air was not observed. Differing from usual vinyl polymerisation, its reaction mechanism is not considered as radical polymerisation. We also examined the possibility of the graft-copolymerisation of ethyleneimine on heat destroyed or hydroperoxyd polymer to ascertain the reaction mechanism.As the results, it might be supposed that the graft cepolymer would be formed by the additional reaction of ethyleneimine with-OH groups or COOH groups on the molecule generated by the irradiation of the polymer.
