摘要： Disclosed is a process for forming a 1H-pyrazolo (1,5-b)-[1,2,4]-triazole compound by ring closing a pyrazoloamidine compound comprising reacting the amidine with an oxidizing agent having a reduction potential vs Ag/AgCl that is more positive than −0.16V and less than +1.43V in the presence of a halogen atom. The invention also discloses certain triazole compounds that are successfully made by the conventional process. The process and compounds of the invention provide improved yields and reduce or eliminate unwanted side-reactions.

摘要： The invention provides rolls, belts and other biasable members having at least one layer or coating of an elastomeric resilient polyurethane formed by reacting (a) a polyisocyanate prepolymer comprising the reaction product of a saturated aliphatic polyisocyanate, a saturated cycloaliphatic polisocyanate, or an aromatic polyisocyanate and a polyol free of aliphatic unsaturation, preferably a polyalkylene glycol in which the alkylene group contains 2 to 8 carbon atoms, and (b) a hardening mixture comprising a polyol of (a) or a diamine free of aliphatic unsaturation, or a mixture thereof and, as a conductivity control agent, from 0.001 to 5.0 weight percent, based on the total weight of (b), of a complex of ethylene glycol or an oligoethylene glycol selected from the group consisting of di-, tri- and tetraethylene glycol with an ionizable antimony halide salt selected from the group consisting of antimony trifluoride, antimony trichloride, antimony tribromide and antimony triiodide.The resistivity of the elastomeric resilient polyurethane coating on the biasable member is controlled or adjusted to within a desired level of resistivity due to the inclusion of the conductivity control agent in the polyurethane elastomer. Additionally, the inclusion of the conductivity control agent in the polyurethane elastomer reduces the sensitivity of the resistivity of the polyurethane coating on the biasable member to changes in relative humidity.

摘要： An apparatus and method for applying a charge features a moving charge applying member having an electrically conductive structure and a semiconductive layer supported upon the conductive structure. The semiconductive layer is formed of a material having a volume resistivity of between about 1.times.10.sup.7 ohm-cm and about 1.times.10.sup.11 ohm-cm. An electrical bias device electrically biases the charge applying member. The electrical bias device applies an electrical bias to the charge applying member so that an electrical current flows from a peripheral surface of the charge applying member through the semiconductive layer to the conductive structure and from the conductive structure through the semiconductive layer to the member to be charged so that a net charge flowing through the semiconductive layer is about zero. The charge flow in the different directions may be simultaneous or at different times.
