OXIDATION OF HALOGENATED POLYMERS AND ANTICAKING HALOGENATED POLYMERS

An oxidized halogenated polymer is prepared by a process comprising: (a) forming an admixture of an acidic oxidizing agent and a suspension of a particulate halogenated polymer in a polar liquid; (b) heating the admixture to a temperature sufficient to initiate the reaction between the polymer and t...

Beschreibung
Zusammenfassung:	An oxidized halogenated polymer is prepared by a process comprising: (a) forming an admixture of an acidic oxidizing agent and a suspension of a particulate halogenated polymer in a polar liquid; (b) heating the admixture to a temperature sufficient to initiate the reaction between the polymer and the oxidizing agent; and (c) continuing the reaction until an oxidized polymer is obtained. At least one addition polymerizable compound is, optionally, grafted to the oxidized halogenated polymer. The oxidized halogenated polymer and graft copolymers thereof have physical properties different from the halogenated polymer and graft copolymers thereof. Certain graft copolymers are noncaking or free flowing.
