The present invention concerns an improved optical method and optical sensing device for determining the levels of polyhydroxyl-substituted organic molecules in vitro and/or in vivo in aqueous media. The range of detection is between about 400 and 800 nm. In particular, a sensory devise is implemented in a mammal to determine sugar levels. Specifically, a dye is combined with a conjugated nitrogen-containing heterocyclic aromatic boronic acid-substituted bis-onium compound in the presence of a s...

The present invention concerns an improved optical method and optical sensing device for determining the levels of polyhydroxyl-substituted organic molecules in vitro in aqueous or organic media. Specifically, a dye is combined with an conjugated nitrogen-containing aromatic heterocyclic aromatic boronic acid-substituted bis-onium compound in the presence of a sugar, such as fructose or glucose. The viologens are preferred as the aromatic conjugated nitrogen containing boronic acid substituted c...

This invention is directed to improved coated products comprising essentially a substrate having a dried, continuous adherent coating of certain colloidally stable polymer latexes thereon which latexes are essentially devoid of conventional wetting agents or surfactants. More particularly, the invention concerns the use as coating materials of polymer latexes containing as the essential ingredient therein, an interpolymer prepared by the essentially continuous addition polymerization in aqueous ...

A process for reducing the heat-seal temperature requirements of films and coatings produced from high vinylidene chloride polymer latexes comprising having present in films or coatings formed from such latexes, prior to fusion thereof, from about 0.5 to about 5 percent by weight of latex polymer solids of an alkyl phenol olefin oxide adduct of the formula ##SPC1## Wherein R.sub.1 is hydrogen or alkyl and R.sub.2 is alkyl wherein the sum of R.sub.1 and R.sub.2 equals from eight to 20 carbon atom...

A process for reducing the heat-seal temperature requirements of films and coatings produced from high vinylidene chloride polymer latexes comprising having present in films or coatings formed from such latexes, prior to fusion thereof, from about 0.5 to about 5 percent by weight of latex polymer solids of a polyoxyethylene sorbitan fatty acid monoester containing from about 10 to 20 moles of ethylene oxide and wherein said fatty acid contains from about 12 to 18 carbon atoms.

A process for reducing the heat-seal temperature requirements of films and coatings produced from high vinylidene chloride polymer latexes comprising having present in films or coatings formed from such latexes, prior to fusion thereof, from about 0.5 to about 5 percent by weight of latex polymer solids of an adduct of an aliphatic alcohol or aliphatic acid and ethylene oxide, such adduct having the formula R-Y CH.sub.2 CH.sub.2 --O .sub.n Z where R is alkyl having from four to about 18 carbon a...

The unsaturation of a hydroxyl-containing compound can be reduced by reaction with a nitrile oxide compound such as tetramethyl terephthalonitrile, N,N'-dioxide. The reaction of a nitrile oxide with terminal unsaturation associated with the preparation of a polyol from propylene oxide reduces the monol content of the polyol composition.

Polybenzazole polymer containing indan moieties may be synthesized. Those polymers can be fabricated into membranes, which are useful for gas separations.

Processes for the preparation of random-fiber thermoset composite sheets by employing a latent curing agent thermoset resin formulation or a coreactant thermoset system such that uncured thermoset composite sheets are formed which can be subsequently formed and cured into articles of manufacture.
