Abstract: A composition comprises poly(arylene sulfide), fiberglass, an additive containing an element selected from among the group consisting of alkaline earth metals, magnesium and beryllium; and silica present in an amount sufficient to increase the shear sensitivity of the composition so that the composition does not drool during molding. A method for providing a composition having reduced drool during molding comprises admixing with a composition containing poly(arylene sulfide) and fiberglass an amount of silica sufficient to increase shear sensitivity of the composition so that the composition has reduced drool during molding.

Abstract: A rapidly crystallizable composition is provided which comprises a poly(arylene sulfide) polymer and a sufficient amount of poly(styrene sulfonic acid salt) to improve the crystallizability of the poly(arylene sulfide) polymer.

Abstract: The tendency of poly(arylene sulfide) resin to cause mold corrosion upon molding is inhibited by mixing, prior to said molding, the poly(arylene sulfide) resin and lithium sulfite alone, or a combination of lithium sulfite and alkali earth metal carbonates, alkali metal or alkaline earth metal borates, or mixtures thereof.

Abstract: Electrical conductivity of a polymeric material is increased by the addition of a compound represented by the formula[CF.sub.3 --(R).sub.0-2 --SO.sub.3 ].sub.x Mwherein M is a metal selected from Groups IB, IIB and VIII of the Periodic Table, x is the valence of M, and each R, if present, is selected independently from CH.sub.2 and CF.sub.2. Examples of M include zinc, cadmium, mercury, copper, nickel and silver. The presently preferred material, for availability and effectiveness, is zinc trifluoromethanesulfonate, in which M is zinc and there are no R groups present.

Abstract: Electrical conductivity of a polymeric material such as poly(phenylene sulfide) is enhanced by exposure to iodine vapor in the presence, optionally, of aluminum.

Abstract: The physical and chemical properties of arylene sulfide polymer articles are improved by contacting with a strong oxidizing agent followed by a step-wise heat treatment at temperatures below the melting point of the polymer.

Abstract: Cyclic sulfonate-sulfate anhydrides are produced by the reaction of an .alpha.- or .beta.-type sulfolene compound with SO.sub.3. Reaction of the cyclic sulfonate-sulfate anhydrides with alcohols produces alkyl esters of hydroxysulfolane sulfonic acids. The cyclic sulfonate-sulfate anhydrides or the alkyl esters of hydroxysulfolane sulfonic acids can be hydrolyzed to hydroxysulfolane sulfonic acids or their respective salts. The latter can be acylated to alkylcarbonyloxysulfolane sulfonic acids.

Abstract: Described herein are novel dihalodicyano alkene compounds having the formula ##EQU1## having from 6 to 38 carbon atoms per molecule, wherein X is chloro or bromo; each R is individually selected from the group consisting of hydrogen, alkyl, cycloalkyl and aryl; and each R' is individually selected from the group consisting of hydrogen, alkyl and cycloalkyl.
