Abstract

It has been shown^1^ that most degradation processes in vinyl polymers can be regarded as polymerization processes in reverse, both occurring by means of a radical mechanism. Under certain experimental conditions, both aggregative and disaggragative processes can proceed simultaneously.

The experiments to be described constitute a specific example of the degradation by a radical mechanism of a vinyl halide co‐polymer in solution.^2^ Dilute solutions of the co‐polymer were used, and the experimental conditions are such that the aggregative reactions are suppressed, while the disaggregative or degradation reactions arc accentuated.

The experiments arose from an observation made in the course of some work involving solutions of a vinylidene chloride co‐polymer, when it was found that solutions of the co‐polymer in tetrahydro‐furan showed a reduction in viscosity when aged at temperatures about 50° c., or above.
