Molecular composites were prepared by the solution blending of poly(ethylene oxide) (PEO) of three different molecular weights with low concentrations of poly(p-phenylene terephthalamide) (PPTA) anion serving as a rigid-rod reinforcement. For all of the composites, the tensile strength, stiffness, a

Molecular composites, in which a small concentration of ionically modified poly(p-phenylene terephthalamide) (PPTA) is dispersed in a poly(ethylene oxide) matrix, have been prepared. With the content of PPTA anion increasing to about 5 wt %, the glass-transition temperature rises and the melting tem
Molecular composites have been prepared by dispersing rigid-rod molecules of ionically-modified poly(p-phenylene terephthalamide) (PPTA anion) in a polar poly(4vinylpyridine) (PVP) matrix. For concentrations up to 5 wt % of the rigid-rod reinforcement, the resulting composites are transparent and po
Different samples of filled poly(vinyl chloride) (PVC) compositions were formulated from PVC, a polar plasticizer mixture consisting of dioctylphthalate (DOP) and a chlorinated paraffin, and variable proportions of a white filler such as barite, calcium carbonate, kaoline, quartz, or talc; a conduct
