Abstract
The ACS blendmer composed of chlorinated poly(ethylene) (CPE) and acrylonitrilestyrene copolymer is known to show an anti-electrification property. The electrostatic property of ACS blendmer and chlorine-containing polymers is studied, attention being given to their chemical structure and molecular motion. In particular, the charge decay process in these polymers is studied. It is found that the anti-electrification property of ACS blendmer depends on the electric property of CPE, and the surface charges are considered to decay quickly through the CPE moiety. The large charge decay constant of CPE, which is in a rubbery state at room temperature, results from the large mobility of the ion accompanied by a vigorous molecular motion. In polymers having a rubbery state, the charges decay more quickly than in those having a glassy state. It is concluded that the electrostatic property of polymers is affected by the molecular motion of polymers as well as the chemical structure.
