Organophosphorus drug-containing agents for the control of parasites in warm-blooded animals

Organophosphorus drug-containing agents for the control of parasites in warm-blooded animals. Ackers, Stanley (Shell Internationale Research Maatschappij B. V., Neth.). Ger. Offen. DE 2637863 10 Mar 1977, 32 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: A61K031-66. PRIORITY: US 75-607397 25 Aug 1975. DOCUMENT TYPE: Patent CA Section: 17 (Foods) Section cross-reference(s): 63 Dry, free-flowing powders or fine granules of organophosphorus anthelmintics were prepd. by mixing the drug with small solid porous particles of a vinyl polymer resin and a styrene-maleic anhydride copolymer. 9002-86-2 and 62-73-7 which are cas registry numbers are also used here. These compns. keep the drug moisture-stable and can be added to feed and then stored, they given an effective dose of the drug throughout the gastrointestinal system of the animal and also in its feces, and they promote the vitality of fetuses and newborns when fed to pregnant animals. For example, 45 g dichlorovos [62-73-7] and 2.25 g Mark QT stabilizer were mixed with 252.75 g Geon 93 [poly(vinyl chloride)] [9002-86-2] porous absorbent particles at 80.degree.. The dry mixt. was cooled and mixed with a soln. of 90 g SMA 1000A (maleic anhydride-styrene copolymer) [9011-13-6] in 350 mL Me2CO and then heated 3 h at 63.degree. to give a dry powder. .

A new method for torsional pendulum analysis of polymers through the glass transition region

A new method for torsional pendulum analysis of polymers through the glass transition region. Fava, R. A.; Chaney, C. E. (Arco/Polym. Inc., Div., Atl. Richfield Co., Monroeville, Pa., USA). J. Appl. Polym. Sci., 21(3), 791-6 (English) 1977. CODEN: JAPNAB. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) The dynamic-mech. loss was measured through the glass transition region for samples molded from 1:3 powd. mixts. of the plastics with wood flour-filled Durez 13527 [62534-52-5] phenolic resin. 62534-52-5 and 9002-86-2 are just another two chemicals used in this study. Dylene 8 (polystyrene) [9003-53-6], poly(2,6-dimethylphenol) [25134-01-4], and their blend, Geon 85297 (PVC) [9002-86-2], Dylark 232 (maleic anhydride-styrene copolymer) [9011-13-6], and their blend were analyzed. .
