Electrolyte compositions for use in cells and batteries that include a crosslinked solid ionically conductive polymer having urethane groups, urea groups, thiocarbamate groups, or combinations thereof, particles, and a salt. Certain electrolyte compositions include a liquid thereby forming a gel electrolyte composition.

Crosslinked polymer electrolyte compositions

A magnetic recording medium, comprising a magnetic layer provided on a nonmagnetizable substrate, wherein the magnetic layer comprises a magnetic pigment dispersed in a polymeric binder, the polymeric binder comprising a resin, wherein the resin comprises a nonchlorinated fluorine-containing vinyl copolymer having pendant nitrile groups, pendant hydroxyl groups, and pendant fluorine-containing groups.

Magnetic recording medium incorporating fluorine-containing, solvent-soluble vinyl copolymer having no vinyl chloride or vinylidene chloride components

This invention is a quaternary ammonium/isocyanate compound having the formula

Self-wetting binders for magnetic media

Magnetic recording medium incorporating fluorine-containing,

A phthalocyanine pigment dispersion using a dispersing polymer having pendant quaternary ammonium salt groups to form a highly dispersed and stable millbase is described. The pigment dispersion is compatible with poly(vinylbutyral) resins and stable in ketone solvents. The pigment dispersion is particularly useful as a charge-generating or charge-transport material in an organic photoconductor construction.

Dispersing polymers for phthalocyanine pigments used in organic

The present invention provides magnetic recording media comprising a magnetizable layer and optionally a backside coating provided on a nonmagnetizable substrate. At least one of the magnetizable layer and the optional backside coating comprises a polymeric binder, wherein the polymeric binder is obtained from reactants comprising a free radical generator and a radiation curable polymer. The radiation curable polymer comprises a plurality of radiation curable, .alpha.-methylstyrene moieties of the formula ##STR1##

Magnetic recording medium having radiation curable binder with

Magnetic recording medium, comprising a magnetic layer provided on a nonmagnetizable substrate, wherein the magnetic layer comprises a magnetic pigment dispersed in a polymeric binder. The polymeric binder comprises a nonhalogenated vinyl copolymer, wherein the vinyl copolymer comprises a plurality of pendant nitrile groups, a plurality of pendant hydroxyl groups, and at least one pendant dispersing group. Preferably, the binder also includes a secondary polymer component.

Magnetic recording medium whose magnetic layer incorporates

The present invention relates to thin film-coated polymer webs, and more particularly to thin film electronic devices supported upon a polymer web, wherein the polymer web is treated with a purifying amount of electron beam radiation.
