The final step is termination of chain growth mostly by radical transfer reaction to monomer [306], whereas combination or disproportionation are observed only to a small extent. The monomer radical is able to start a new chain. The most widely used procedures for preparation of commercially PVC resins are, in order of their importance, suspension, emulsion, bulk, and solution polymerization. A common feature of the first three methods is that PVC precipitates in liquid VC at conversions below 1%. The free polymerization of VC in a precipitating medium exhibits an accelerating rate from the beginning of reaction up to high conversion [307]. This behavior is called autoacceleration and is typical for heterogeneous polymerization of halogenated vinyls and acrylonitrile [308]. [Pg.192]

The conversion of aryl allylic alcohols into halogenated vinyl ketones has been achieved (Scheme 7.114) [179]. The process occurred under very mild conditions using oxalyl halides and was generally regioselective for the formation of the a-substitution product. A number of electron-donating and electron-withdrawing groups were well tolerated by the chemistry, provided they were attached to the arene in specific locations. Best results... [Pg.634]
