摘要： This invention provides cellulose ester fibers having an intermediate degree of substitution per anhydroglucose unit (DS/AGU) along with pigments which act as photooxidation catalysts. The fibers are useful as filter materials for tobacco products. The filter materials thus provided are easily dispersible and biodegradable and do not persist in the environment.

摘要： Disclosed are processes for the preparation of cyclohexanedicarboxylic acids by the non-catalytic hydrolysis or acidolysis of dialkyl cyclohexanedicarboxylate esters. The processes provide a means for converting dialkyl cyclohexanedicarboxylate esters to cyclohexanedicarboxylic acids without the co-production of solid by-products which present disposal problems.

摘要： The invention relates to bichromophoric benzotriazole-styrene ester compounds which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing a stabilizing amount of the bichromophoric composition to prevent such degradation. These stabilizers are effective in the presence of other additives commonly employed in polymeric compositions including, for example, pigments, colorants, fillers, reinforcing agents and the like. These ultraviolet stabilizers may also be incorporated into the organic compositions in the polymer melt or dissolved in the polymer dope, coated on the exterior of the molded article, film or extruded fiber.

摘要： Polyolefins are rendered resistant to degradation upon exposure to heat by incorporating therein a stabilizing amount of a synergistic combination of a phenol-terpene resin, a sulfur-containing secondary antioxidant and a phosphonitrilic composition derived rom a phosphonitrilic halide and certain hydroxy compounds. The above synergistic combination is especially effective for stabilizing polyolefins containing carbon black.
