DIELECTRIC RELAXATION STUDIES OF ETHYLENE-CARBON MONOXIDE COPOLYMERS.

Abstract

Dielectric relaxation studies were carried out on copolymers of ethylene and carbon monoxide containing up to 1.0% carbon monoxide. The results obtained are similar to those of oxidized polyethylene (alpha, beta, and gamma peaks); however, the position of the alpha peak (crystalline in origin) varies with CO concentration, moving to lower temperatures as the concentration is increased. The distribution of relaxation times associated with the alpha peak is narrowed markedly as temperature is increased and tends to a single relaxation time. This is in contrast to observations on oxidized polyethylene which have indicated no variation with temperature. (Author)
