    Abstract: This invention is directed to a new thermal stabilizer system for cellulose esters and their commercially useful formulated compositions which can be molded, shaped and otherwise processed in a thermoplastic condition at elevated temperatures to provide products having (1) better molecular weight retention and (2) less discoloration after thermal processing when compared to similar cellulose ester compositions containing prior art stabilizers.

    Abstract: Acrylic synthetic fibers having excellent touch and luster properties are produced, wherein such fibers are prepared from a copolymer comprising 30 weight % or more of acrylonitrile, 70 weight % and less of vinyl chloride and/or vinylidene chloride and from 0 to 10 weight % of other polymerizable vinyl monomers. The copolymer also contains at least one metallic compound which is present in an amount of from 0.1 to 8.0 parts per 100 parts of copolymer and, additionally, at least one cellulose derivative which is present in an amount from 1.0 to 8.0 parts per 100 parts of the copolymer. Fibers produced from such copolymer have the touch and luster very similar to natural animal hair.

    Abstract: MEMBRANES SPECIALLY ADAPTED TO PREFERENTIALLY PERMIT THE PASSAGE OF RELATIVELY PURE WATER THROUGH THEM, WHILE RESISTING THE PASSAGE OF DISSOLVED SALTS MUST CONVENTIONALLY BE KEPT WATER-WET IN ORDER TO RETIAN THIS ABILITY TO EXCLUDE SALTS. DRY, REWETTABLE, STABILIZED MEMBRANES IN WHICH THIS DESIRABLE PROPERTY IS PRESERVED, CAN BE MADE BY TREATING THE WET MEMBRANE FIRST WITH A WATER-MISCIBLE SOLVENT, THEN WITH A NON-POLAR ORGANIC SOLVENT AND FINALLY DRYING THE MEMBRANE. THE PRESENCE OF A WATER-SOLUBLE POLYOL IN THE DRY MEMBRANE RESULTS IN STILL BETTER PROPERTIES.
