The compounds (NH4)3AsS4· 5 NH3 (1) and (NH4)3SbS4· 8 NH3 (2) were prepared by the reaction of Na3AsS4 and Na3SbS4 with a proton-charged ion exchange material in liquid ammonia and characterized by low temperature single crystal X-ray structure analysis. The ammonium-ammoniates show H3N-H···N-hydrogen bonds between the ammonium ion and ammonia molecules ranging from 1.86 to 2.55 Å (DHA-angles: 145 - 173°) and H3N-H···S-bonds to the thioanions between 2.36 and 2.97 Å (DHA-angles: 130 - 176°). The former of the interactions are responsible for the formation of [(NH3)2H]+, [(NH3)3H]+ and [(NH3)4H]+-complexes, the last two of which were characterized by X-ray analysis for the first time.

Comprehensive Performance

Abstract: Phenolic-Formaldehyde(PF) foam was improved by co-foaming of PF resin modified using Nitrile Butadiene Rubber Power(NBRP) and other additives in the closing mould at 70°C. The effects of amount of NBRP on mechanical properties and microscopic structure of NBRP-PF foam were investigated. The results indicated that NBRP can improve the mechanical properties.When 2 percent NBRP of foam was used, the comprehensive performance was the best. This could be a consequence of cooperation of NBRP and PF resin.

Low Temperature Resistance

The preparation method of low-temperature resistance nitrile-butadiene rubber coat-metal sealing gasket was introduced. The type and the dosage of curing agent, reinforcing agent and other additives were considered, the optimum technological factor was determined. Use of such nitrile-butadiene rubber coat-metal sealing gasket, its low temperature resistance and oil resistance were good enough for the seals which work at -40 -160 .

Nitrile Butadiene Rubber

We invented a dispersion analysis program that analyzes the relaxation processes from dielectric permittivity based on a combination of the Havriliak–Negami and conductivity contribution functions. By applying the created program to polymers such as nitrile butadiene rubber (NBR) and ethylene propylene diene monomer (EPDM), several relaxation processes were characterized: an α process due to segmental motions of the C-C bond, an α′ process attributed to fluctuations in the end-to-end dipole vector of the polymer chain, the conduction contribution by the filler observed above room temperature, and secondary relaxation processes β and γ of motion for the side group in NBR. In the EPDM specimen, the β process associated with the rotational motion of the side groups, the α process associated with the relaxation of local segmental motion, and the αβ process associated with the origin of the β process at high temperatures above 305 K were observed. The Maxwell–Wagner–Sillars effect and conduction contribution were also presented. The molecular chains responsible for the relaxation processes were assigned by building molecular models of the two polymers. The temperature dependence of the relaxation strength and the shape parameters that characterize the process were investigated. From the temperature-dependent relaxation analysis, the merged αβ process, activation energy, and glass transition temperature were determined and compared.
