Abstract: Rubber and plastic accelerator formulations of the present invention are directed to formulations containing an accelerator compound comprised of an organic-based quaternary ammonium salt. Preferably, the accelerator compound of the present invention is comprised of a quaternary ammonium salt selected from the group consisting of trimethylbetahydroxyethyl ammonium hydroxide (TMBHEAH), carboxymethyltrimethyl ammonium hydroxide (CMTAH), methylallylbenzylphenol ammonium iodide, benzyltriethyl ammonium chloride, hexadecyltrimethyl ammonium chloride imidazolium compounds. As particularly preferred embodiments, the accelerator formulations are comprised of a choline based compound comprised of trimethylbetahydroxyethyl ammonium hydroxide and/or of a betaine compound comprised of carboxymethyltrimethyl ammonium hydroxide.

Abstract: The invention provides a processing aid and method for lubricating and improving the processability and releasability of rubber and plastic without adversely affecting and, in certain instances, improving the physical properties of the rubber or plastic such as adhesion, tack, modulus and tensile strength. The processing aid comprises a pre-formed homogeneous mixture of at least one silicone fluid lubricant and at least one peptizing agent. A preferred processing aid also includes a silicone fluid wetting agent, which affords decreased vulcanization times and increased production rates.

Abstract: A partially-neutralized, fatty-acid modified alkylbenzene sulfonic acid is useful as a processing aid for use with natural, synthetic or reclaimed rubber, and it is useful in the mastication and peptizing steps of rubber processing, as well as in dispersing and emulsifying additives for the rubber and in improving the wetting characteristics of the rubber. The partially-neutralized, fatty-acid modified sulfonic acid may be formulated into a composition having particular utility as a lubricant for rubber by mixing with a fatty acid amide, a polyethylene glycol, a wax and, optionally, a fluorinated surfactant.

Abstract: This invention is concerned with a novel rubber processing aid, as well as with the use of that aid for improving the processing of rubber. More specifically, the present invention is concerned with the formation of an amine salt of an aralkylsulfonic acid through the deposition of an amine and an aralkylsulfonic acid on a natural or synthetic clay base. This invention is further concerned with the use of said aralkylsulfonic salt composition, optionally modified with additives such as a thioether or a long chain fatty acid, for improving the processing of natural and synthetic rubber.

Abstract: A particulate, relatively free-flowing rubber processing aid capable of imparting release properties and improved flow characteristics to rubber during compounding and molding of the rubber, comprises petrolatum and particulate clay in proportions of petrolatum to clay of from about 1:4 to about 4:1. The amount of processing aid which is effective to impart improved release and flow properties is from about 0.1 to about 5 weight percent of the total rubber compound.

Abstract: Compositions containing salts of aromatic sulfonic acids, long chain fatty acids and thioethers are useful in the processing of natural and synthetic rubber by permitting the usual peptizing step of such processing to be omitted.

Abstract: Improved rubber compounding is achieved by adding the zinc oxide and fatty acid conventionally employed as accelerator activators in the form of a zinc salt of the fatty acid dispersed in an alkylphenoxy polyglycol.

Abstract: Compositions composed of an alkylphenoxy polyethylene glycol, an amine or quaternary ammonium salt of an organic acid and an amide facilitate blending of particulate poly(vinyl chloride) resins during fabrication of the resin into molded or extruded articles.

Abstract: This invention is directed to novel compositions which aid in the processing of natural and synthetic rubber by permitting the usual peptizing step of such processing to be omitted. These compositions contain salts of aromatic sulfonic acids as well as long chain (fatty) acids as essential ingredients.
