ELECTRICAL RESISTIVITY OF A POLYVINYL CHLORIDE DIBUTYL PHTHALATE PLASTISOL,
Abstract
Electrical volume resistivity techniques have been employed to study the hardening and proper ties of a polyvinyl chloride-dibutyl phthalate plastisol. It is shown that resistivity measure ments can be employed to follow the hardening of plastisol systems and yield information useful in elucidating the nature of the hardening process. This process appears to occur in two stages. In ordder to obtain the maximum extent of hardening, it is necessaconduct the final stage in the hardening process at a temperature above the glass transition temperature of the polymeric component. Plasticized systems exhibit a non linear dependence of resistivity vs. temperature. For a number of plasticized polymers a linear relationship is found to exist between the loga rithm of the magnitude of the resistivity at 25 C and the activation energy for the electrical conduction process. This relationship is dis cussed and a possible explanation of its signif icance is given. (Author)
