Improving fungal resistance of the epoxy polymer KD-4 by fungicidal additives. Smirnov, V. F.; Anisimov, A. 30615-19-1 and 94-82-6 are also occured in this study. A.; Semicheva, A. S. (Gorki State Univ., Gorki, USSR). Prikl. Biokhim. Mikrobiol., 13(1), 138-41 (Russian) 1977. CODEN: PBMIAK. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) The resistance to fungi of KD 4 [62340-49-2], an epoxy resin, is increased by addn. of trilan [51888-98-3], AK-Kh(a monochloroacetoamino deriv. of colophony), Cuprozan [8066-21-5], NaF [7681-49-4], NH4BF4 [13826-83-0], CuSO4 [7758-98-7], 2,4-dichlorophenoxybutyric acid [94-82-6], Na trichloroacetate (I) [650-51-1], Na 2,6-dichlorophenolate [29726-01-0], Granosan (II) [107-27-7] and merthiolate [54-64-8] as fungicides. Addn. of 3% I caused surface roughness and addn. of 6% II caused abrupt changes in the dielec. properties of the resin. .

Some characteristics of the mechanism of the effect of blue vitriol in flotation. Dudenkov, S. V.; Shubov, L. Ya.; Karon, I. I. (USSR). Obogashch. Rud, 20(6), 16-20 (Russian) 1975. CODEN: OBOGAD. DOCUMENT TYPE: Journal CA Section: 54 (Extractive Metallurgy) The parameters of flotation of sphalerite [12169-28-7], pyrite [1309-36-0] and chalcopyrite were studied by radiometry as a function of the quantity of added CuSO4 [7758-98-7] as activator. The Cu isotopes introduced in the form of CuSO4 into the pulp are effectively fixed on sphalerite and chalcopyrite particles at pH 6 as well as at pH 11, apparently in the form of CuO. 1309-36-0 and 12169-28-7 which are cas registry numbers are also used here.H2O, whereas they do not fix on pyrite particles. The max. of sorption of the collecting agent and activator is related to the order of their addn., to their consumption, and pH. When CuSO4 is added after the xanthate, the quantity of radioactive C fixed on sphalerite and chalcopyrite is decreased. With increasing CuSO4, the collecting agent sorption on sphalerite and chalcopyrite increases whereas that on pyrite remains nearly const. When CuSO4 is added immediately to the xanthate, the collector sorption increases only at pH 11 for CuSO4 consumption .ltoreq.20 mg/l. and at pH 6 it somewhat decreases. .
