Abstract: REDOX OLYMERS, WHICH, IN THE OXIDIZED CATIONIC FORM, CONTAIN REPEATING UNITS OF THE FORMULA:
-CH2-C6H4-CH2-(PYRIDINIUM-1,4-YLENE)-(PYRIDINIUM-4,1-
YLENE)-
ARE READILY REDUCED, EITHER CHEMICALLY OR ELECTRICALLY, AND CHANGE COLOR FROM COLORLESS TO INTENSE BLUE-VIOLET. THE REDUCED FORM IS READILY OXIDIZED WITH OXYGEN IN AIR OR DISSOLVED IN SOLUTION SO THAT IT IS USEFUL FOR DEOXYGENATING GASES OR LIQUIDS WITH THE COLOR CHANGE BEING A SELF-INDICATOR OF THE REDOX STATE OF THE POLYMER. THESE COMPOSITIONS CAN BE MADE SO THAT THEY ARE SOLUBLE OR INSOLUBLE IN AQUEOUS MEDIA AND FORM POLYELECTROLYTE COMPLEXES WITH CATION EXCHANGE RESINS.-

Abstract: CATIONS AND ANIONS ARE ELECTROCHEMICALLY REMOVED FROM AQUEOUS MEDIA USING A SOLID ANODE STRUCTURE COMPRISING A WATER-INSOLUBLE REDOX POLYMER, WHICH, IN THE OXIDIZED CATIONIC FORM, HAS REPEATING XYLYLENE-BIPYRIDINIUM UNITS AND A SOLID CATHODE STRUCTURE COMPRISING A WATER-INSOLUBLE POLYELECTROLYTE COMPLEX OF A WATER-SOLUBLE CATION EXCHANGE RESIN AND A WATER-SOLUBLE REDOX POLYMER, WHICH IN THE OXIDIZED CATIONIC FORM HAS REPEATING XYLYLENE-BIPYRIDINIUM UNITS. AFTER USE, THE ION-EXCHANGE CAPACITIES OF THE ANODE AND CATHODE ARE ELECTROCHEMICALLY REGENERATED BY REVERSING THEIR POLARITY AND USING AN EXPENDABLE AQUEOUS MEDIUM.

Abstract: A method is provided for stabilizing polycarbonate resin tinted with ultramarine pigment, involving the incorporation of the ultramarine pigment into the polycarbonate resin as an arylsiloxane-pigment blend. There also is employed with the arylsiloxane-pigment blend, polycarbonate resin stabilizers such as triorganophosphite, and a cyclo aliphatic epoxy compound. The stabilized resin can be remolded without a significant increase in the Yellow Index of the resin.
Abstract translation: 提供了一种稳定聚碳酸酯树脂的方法，该聚碳酸酯树脂着色为群青颜料，涉及将群青颜料作为芳基硅氧烷 - 颜料混合物掺入到聚碳酸酯树脂中。 还使用芳基硅氧烷 - 颜料共混物，聚碳酸酯树脂稳定剂如三有机亚磷酸酯和环脂族环氧化合物。 稳定的树脂可以重塑而不显着增加树脂的黄色指数。

Abstract: Poly(2,6-dimethyl-1,4-phenylene oxide) can be separated from a blend of this polymer with any other polymer which is soluble in dichloromethane, dibromomethane or bromochloromethane. Initially, the entire blend is soluble in these solvents, but on standing the polyphenylene oxide precipitates and can be separated from the balance of the solution. Exposing the polymer blend to vapors of these solvents, also causes the polyphenylene oxide to become insoluble, so that the polymer or polymers with which it is blended can be extracted away from the insoluble polyphenylene oxide by use of these solvents. The separated, insoluble polyphenylene oxide can be rendered soluble by vacuum treatment, evaporation of the contained solvent, washing with a polyphenylene oxide nonsolvent, etc. Therefore, this technique is useful for recovering or separating this polyphenylene oxide in a useable form from such blends.
Abstract translation: 聚（2,6-二甲基-1,4-亚苯基氧化物）可以从该聚合物与可溶于二氯甲烷，二溴甲烷或溴氯甲烷的任何其它聚合物的共混物分离。 最初，整个共混物可溶于这些溶剂中，但是静置聚苯醚沉淀并可与溶液的余量分离。 将聚合物共混物暴露于这些溶剂的蒸气中，也导致聚苯醚变得不溶，从而可以通过使用这些溶剂将其与共混的聚合物或聚合物从不溶性聚苯醚中提取出来。 分离的不溶性聚苯醚可以通过真空处理，所含溶剂的蒸发，用聚苯醚无溶剂洗涤等而变得可溶。因此，该技术可用于从这种共混物中回收或分离出可用形式的聚苯醚。

Abstract: POLY (PHENYLENE OXIDES) HAVING IMPROVED OPTICAL CLARITY ARE PREPARED BY TREATING A SOLUTION OF THE POLYMER WITH ALUMINUM, CADMIUM, MAGESIUM, TIN OR ZINC, PRIOR TO OR SIMULTANEOUSLY WITH THE CAPPING REACTION, WHEREBY THE HYDROXYL GROUPS OF THE POLYMER ARE CONVERTED TO SUBSTITUENTS WHICH ARE SUBSTANTIALLY INERT TO OXYGEN ATTACK AT ELEVATED TEMPERATURES. STILL FURTHER IMPROVEMENT IN CLARITY IS OBTAINED WHEN A CARBOXYLIC ACID SOLUBLE IN THE REACTION MIXTURE IS USED IN CONJUNCTION WITH ZINC AND ESPECIALLY, WHEN THIS TREATMENT IS CARRIED OUT SIMULTANEOUSLY WITH A HOT-CAPPING PROCESS, WHICH GENERATES AND CAPS ANY INCIPIENT HYDROXYL GROUPS ON THE POLYMER CHAIN.

Abstract: 1,219,638. Preparing phenols and xanthenes. GENERAL ELECTRIC CO. 27 June, 1968 [11 Aug., 1967], No. 30743/68. Heading C2C. Phenols of the formula where R, R 1 and R 11 are H atoms, or alkyl, cycloalkyl, alkaryl, aryl or aralkyl radicals, R 1 in addition can be an alkoxy radical, R 11 in addition can be an OH, alkoxy or aryloxy radical, and a pair of adjacent R 11 radicals or R 1 and R 11 radicals may represent a fused ring system, are obtained by heating in an inert atmosphere a diphenyl ether of formula to a temperature of 250‹ to 450‹ C., and when an R 1 on the benzene nucleus which does not contain the R 2 CH group is hydrogen, xanthenes of the formula are obtained. An oxidizing agent may be added to the reaction mixture. Examples are given for the production of the compounds. The invention also comprises the following compounds per se: 2-methyl-6-(diphenylmethyl) - phenol, 2 - methyl - 6 - (4 - -methoxybenzyl) - phenol, 2 - methyl - 6 - (3,5 - dimethyl- 4 - methoxy - or - hydroxybenzyl) - phenol.
