  • Process for polymerizing vinyl chloride polymers with iodinated chain transfer agents
    Patent number: 5455319
    Abstract: The present invention to a method of synthesizing poly(vinyl halide) by means of a free radical polymerization which mimics a "living" radical polymerization in the presence of an iodine containing chain transfer agent containing at least one iodine atom bonded to a primary carbon atom and having the formula:R--CH.sub.2 I (I)R--CHX I (II),R--CH(X)--CH.sub.2 I (III),R--CH(X)--CHX I (IV), orR--CH(X)--CH.sub.2 --CHX I (V),wherein X is fluorine, chlorine, bromine, or iodine, R is hydrogen, C.sub.1, C.sub.2, C.sub.3, C.sub.4, C.sub.5 alkyl, any of which are linear or branched, cyanoalkyl, cyclohexyl, methyl cyclohexyl, phenyl, benzyl, and halogenated or oxygenated derivatives thereof.In accordance with the invention there is further provided a method of synthesizing 1-halo-1-iodoethane by reacting hydrogen iodide with vinyl chloride or vinyl fluoride in the presence of an iodine generating catalyst under certain specified conditions.
