## Abstract The specific volume of a polyvinyl chlorideโ€polyvinyl acetate copolymer was studied as a function of temperature. It was found that two secondโ€order transition temperatures exist, one at 30ยฐC. and the other at 77ยฐC. The lower transition temperature has not been reported previously. Diff

## Abstract Blends of the conducting polymer, polypyrrole (PPy), and in the insulating host polymers, polyvinyl acetate (PVAc), polystyrene (PS), and polyvinyl chloride (PVC) resin, have been prepared chemically. Threshold conductivities occur at about 5% for PPy in blends with host polymers. The c

## Abstract The minimum free volumes involved in the diffusion of gases of various sizes through a copolymer of polyvinyl chlorideโ€“polyvinyl acetate have been calculated by use of equations developed by F. Bueche. It was found that as the gas diameter of the diffusant increased, the minimum free vo
