A new molybdenum(VI) complex Cs2(NH4)2[Mo3O8(C2O4)3] (CAMO) has been prepared and characterized by chemical analysis and IR spectral studies. Thermal decomposition studies have been made using TG, DTA and DTG techniques. The compound is anhydrous and stable up to 160°C. Thereafter it decomposes in three stages. The first and the second stages occur in the temperature ranges 160–220°C and 220–280°C to give the intermediate compounds having the tentative compositions Cs4(NH4)2[Mo6O16(C2O4)3(CO3)2] and Cs4[Mo6O16(C2O4)2(CO3)2] respectively, the later then decomposing to give the end product Cs2Mo3O10 at 370°C. The end product was characterized by chemical analysis, IR spectral and X-ray studies.
Abstract
Radiation induced grafting of acrylonitrile (ACN) on ethylene-propene diene terpolymer (EPDM) rubber film was investigated by mutual radiation grafting technique. Effect of experimental variables viz. radiation dose, dose rate, type of solvent and monomer content on extent of grafting was studied. From the kinetic studies a mathematical relation R g α[M]0.7 D 0.68 showing non-linear relationship for rate of grafting with monomer concentration and dose was deduced. The grafted samples showed increased hardness and oil resistance.
