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

High molecular-weight aromatic polyamides were obtained from 1,5-and 2,6-bis-(4'-carboxy-4-phenylenoxy-sulfony1)naphthalene by direct polycondensation reaction in N-methyl-2pyrrolidone with various aromatic diamines, using triphenyl phosphite and pyridine as condensing agents. The polymers were char
