In the title compound, C(10)H(12)N(2)S, one of the C atoms of the cyclo-hexene ring (at position 6) and the methyl group attached to it are disordered over two sets of sites in a 0.650 (3):0.350 (3) ratio. The cyclo-hexene ring in both the major and minor occupancy conformers adopts a half-chair conformation. The thio-phene ring is essentially planar (r.m.s. deviation = 0.05 Å). In the crystal,...

The free radical dispersion polymerization of styrene (St) and methyl methacrylate (MMA) initiated by poly(oxyethylene) (PEO) macroazoinimer (MIM-400) in water/ethanol, was investigated at three different temperatures (50, 60 and 80 8C) for seven polymerization times (3, 6, 9, 12, 24, 36 and 48 h). PStPEO and PMMA-PEO networks were obtained. In each case, polymer gel fractions depend on the pol...

The mechanical relaxation behavior and microstructure of a series of novel norbornylPOSS organic-inorganic copolymers have been investigated. We have examined the influence on physical properties of both the weight fraction of POSS-norbornyl monomer and the corner group composition. POSS refers to the polyhedral oligomeric silsesquioxane inorganic/organic macromer, which is composed of an inorg...

A series of microcosm experiments were performed to determine the effectiveness of various gaseous electron donors (including hydrogen, 1-hexene, ethyl acetate, and liquefied petroleum gas [LPG]) for supporting biological perchlorate reduction under different electron donor concentrations and soil moistures. Under high soil moisture (16% w/w) conditions, complete or partial perchlorate degradat...

Binucleating multidentate amine bis(phenolate) ligands with rigid terphenyl backbones were designed to support two zirconium centers locked in close proximity. Polymerizations of propylene or 1-hexene with the synthesized bimetallic precatalysts resulted in polymers with significantly higher isotacticity (up to 79% mmmm) in comparison to the stereoirregular polymers produced with previously rep...
