METHOD OF PSEUDO-LIVING RADICAL POLYMERIZATION OF POLYVINYL HALIDE AND PREPARATION OF RESIN AND CHAIN TRANSFER AGENT BY THE METHOD

摘要

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-CH2 I (I> R-CHX I (II), R-CH(X)-CH2 I (III), R-CH(X)-CHX I (IV), or R-CH(X)-CH2-CHX I (V), wherein X is fluorine, chlorine, bromine, or iodine, R is hydrogen, C1, C2, C3, C4, C5 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.
