Notes:
While it is accepted that the high-energy irradiation of poly (vinyl chloride) produces a predominately crosslinked material, confusion exists about the vinyl chloride-vinylidene chloride copolymer system. Degradation is generally assumed. We have shown that crosslinking (or endlinking) predominates over chain scission in several poly (vinyl chloride-vinylidene chloride) systems. The relative amounts of the two reactions are a function of vinylidene chloride content in the copolymer. While crosslinking is increased at increased temperatures during irradiation, and decresed in the presence of oxygen, a much larger effect is exerted by the physical form (or heat history) of the solid copolymer itself.
