摘要： 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. The resulting product of the reaction is a high yield, high purity 1-chloro-1-iodoethane or 1-fluoro-1-iodoethane. The poly(vinyl halide) resin is obtainable under conventional temperatures of polymerization and the chain transfer agents included herein perform consistently over repeated runs, hence useful for commercial manufacturing. The resin obtained has reduced molecular weight and polydispersity, good thermal stability, and enhanced mechanical properties, compared to poly(vinyl halide) conventionally formed by free radical methods at higher temperatures and/or with the use of conventional chain transfer agents for vinyl halide polymer.
摘要翻译：本发明涉及一种通过自由基聚合合成聚（乙烯基卤化物）的方法，该方法在含有至少一个与原子碳原子键合的碘原子的含碘链转移剂存在下模拟“活性”自由基聚合并且具有下式：R-CH 2 I（I）R-CHX I（II），R-CH（X）-CH 2 I（III），R-CH（X）-CHX I（IV）或R-CH （X）-CH 2 -CHX I（V），其中X是氟，氯，溴或碘，R是氢，C1，C2，C3，C4，C5烷基，其中任何一个是直链或支链的，氰基烷基，，甲基环己基，苯基，苄基及其卤化或氧化衍生物。根据本发明，还提供了在特定条件下，在碘发生催化剂存在下，使碘化氢与氯乙烯或氟乙烯反应合成1-卤代-1-碘乙烷的方法。所得反应产物是高产率，高纯度的1-氯-1-碘乙烷或1-氟-1-碘乙烷。聚（乙烯基卤化物）树脂可以在常规聚合温度下获得，并且本文所列的链转移剂一贯地重复进行，因此可用于商业制造。与通常在较高温度下通过自由基方法形成的聚（卤乙烯）和/或使用常规的乙烯基卤化物聚合物链转移剂相比，所获得的树脂具有降低的分子量和多分散性，良好的热稳定性和增强的机械性能。

摘要： A process for depolymerizing polymers by selective, partial oxidation at supercritical or near supercritical conditions for water and wherein supercritical water or water near supercritical conditions is used as a solvent and reforming agent, is used to produce relatively high yields of the monomers originally used to produce the polymers. The invention provides an environmentally friendly process for recycling polymeric waste materials to generate valuable polymer feedstock in a closed oxidation process which is free of hazardous stack emissions. The polymers which can be recycled in accordance with the process can include typical amounts of conventional additive and other impurities without significantly affecting the overall conversion.
