An efficient procedure was developed for preparing bis(3,5-di-tert-butyl-4-hydroxyphenyl) polysulfides in the presence of phenolic Mannich bases. The antioxidative activity of the resulting bis(polysulfides) in rubbers of various structures and in their vulcanizates was examined. 相似文献

Physicomechanical and rheological properties of isotactic polypropylene modified with a high-molecular-weight amorphous polymer, polyoctene, were studied. Modification of polypropylene with polyoctene allows the impact resilience and relative elongation to be increased relative to the initial polypropylene and the processing temperature to be decreased. 相似文献

A comparative study of dipyrido-and dibenzo-substituted 1,4-diazines {dipyrido[f,h]quinoxaline (dpq), dipyrido[a,c]phenazine (dppz), 6,7-dicyanodipyrido[f,h]quinoxaline (dicnq), dibenzo[f,h]quinoxaline, dibenzo[a,c]phenazine, 6,7-dicyanodibenzo[f,h]-quinoxaline}, o-phenantroline (phen), and also of the complexes [Pt(N∧C)(N∧N)]+[(N∧C)? are deproronated forms of 2-phenylpyridine and 2-(2-thienyl)pyridine; (N∧N) is ethylenediamine, phen, dpq, dppz, dicnq] was carried out by the methods of 1H NMR, electronic absorption, and emission spectroscopy and by cyclic voltammetry. It was found that in frozen solutions of [Pt(N∧C)·(N∧N)]+ complexes the photoexcitation energy decay from two lowest in energy electronic excited states has isolated character and is localized on {Pt(N∧C)} and {Pt(N∧N)} metal-complex fragments: (d-π N∧C * ) and (d-π phen * ) [(N∧N) = phen, dpq, dicnq)] or (d-π N∧C * ) and (π-π diaz * ) [(N∧N) = dppz]. Thermal quenching of the luminescence from the (d-π phen * ) and (π-π diaz * ) states gives rise to luminescence of the complexes in liquid solutions at 293 K only from the (d-π N∧C * ) state. 相似文献
