ABSTRACT:
The monomer content in chlorinated hydrocarbon plastic materials, as for example articles made from polymers of chloroprene vinyl chloride and vinylidene chloride, is substantially reduced by applying ionizing radiation in low dosage levels, e.g. 0.05-2 megarad to the material, either to the fully formed article, or the pellets from which the articles are molded or to the ground resin powder from which the pellets are formed.
