ON THE QUESTION OF IMPROVING SOME POLYVINYL CHLORIDE POLYMERS AND A METHOD OF IMPROVING THEIR TOXICITY,
Abstract
A method is developed for 'improving' the polyvinyl chloride tapes for the purpose of decreasing their gas emanation. The overall gas emission of organic substances from the 'improved' specimens of polyvinyl chloride tapes as a result of the treatment with 50% urea solution is reduced by a factor of 2 1/2. The 'improved' polyvinyl chloride tapes give off volatile chemical substances in small concentrations, which with long duration of their action on the organism cause only a weak biological effect. As a result of the treatment with a solution of urea there is an improvement in the electrical insulation properties of the polyvinyl chloride tapes serving the purpose for which the materials are intended without change in their strength characteristics.
