摘要:
The present invention relates to a method for preparing polymeric films, preferably electroactive films, with enhanced physical properties by the steps of applying to a substrate a solution of a polymer containing pendant labile solubilizing groups, then removing the solvent and a sufficient concentration of the labile solubilizing groups render the polymer less soluble in the solvent than before the labile groups were removed. It is believed that the removal of pendant soluble groups a) permits optimization of the semiconducting backbone for charge transport performance, b) allows direct control of microstructure in the final film, and c) renders the final film more robust during subsequent process steps needed to construct multilayer devices.

The present invention relates to a pentathienyl-fluorene copolymer having structural units represented by formula (I): here R and R′ are each independently a substituent or H. The invention also relates to a transistor containing this copolymer. The present invention addresses a problem in the art by providing an electroactive device with exceptionally low hysteresis.

Battery electrolyte solutions contain certain ester solvents, a lithium salt and vinylene carbonate, vinyl ethylene carbonate or fluoroethylene carbonate. Batteries containing these solvents have excellent specific discharge capacities and reduced weight compared to batteries in which the electrolyte is based on ethylene carbonate.

The present invention relates to nonlinear optical material comprising nonlinear optical dihydroxy arylhydrazones and to nonlinear optical materials comprising compositions containing at least one divalent moiety of nonlinear optical arylhydrazones. The present invention also relates to polyesters, polyestercarbonates, polycarbonates, polyethers, and poly(hydroxy ether) polymers, incorporating the dihydroxy arylhydrazone as recurring divalent moieties in the backbone of the polymer. The polymeric compositions of the present invention have high glass transition temperatures and exhibit stable nonlinear optical activity at high temperatures over a period of time.
摘要:
Poly(hydroxy amide ethers) which exhibit high barrier properties are prepared by contacting one or more amide-containing bisphenols and an epihalohydrin. These polymers are suitable for use in the manufacture of articles such as rigid containers and flexible films exhibiting high barrier to oxygen transmission in moist environments.
摘要:
A system for periodic and real-time processing of accounts. The system operates in a bulk mode and an error mode. A bulk component concurrently processes a set of eligible accounts with a set of dependent tasks, and a removal component removes one or more accounts from the eligible accounts if an error is associated therewith. In bulk mode, each task fetches only the required set of accounts/subscriptions/payment instruments for processing. In error mode (retry/reprocess mode), if an account encounters an error for a task in the bulk mode, the account drops is removed from bulk mode and becomes ineligible for fetching in any future bulk-mode task processing. Error-mode processing tests and processes all tasks sequentially for an errored account until the account state is in par with the accounts being processed by bulk mode. Then the account is removed from error mode processing and is picked up appropriately by bulk-mode processing.

Embodiments of the present disclosure include processes for autodepositing a coating on a metal surface, a method of producing a coating on a non-stainless steel metal substrate surface, and an alkaline coating composition, where the process for autodepositing a coating on a metal substrate surface includes immersing at least a portion of the metal substrate surface in a coating composition that includes a latex and an amount of base sufficient to raise the pH of the composition to an alkaline pH, where the coating autodeposits on the metal substrate surface, as metal ions from the metal substrate surface interact with the alkaline coating composition.

Fast hardening aqueous latexes and coating compositions, including paints such as traffic paints, comprising a triazole exhibit less plate out onto process metal surfaces compared to similar triazole-free compositions.
