A polyurethane polymer and method of preparing it is described. The process requires the combination of a soluble polyol with a di- or polyisocyanate under densified fluid conditions. The process to prepare a waterborne polyurethane involves the utilization of a polyol containing ionic or latent ionic groups which must undergo preneutralization before combining with the di- or polyisocyanate under densified fluid conditions. The resulting polyurethane is substantially free of an organic solvent.

Synthesis of condensation polymers in densified fluids

Water-treatment compositions are provided which contain a water-soluble, water-treatment polymer and, optionally, additional water-treatment chemicals. The polymers are prepared from water-treatment monomers and a photo-inert, latently-detectable moiety which is covalently bonded to the polymer backbone. When the residue of the photo-inert moiety is contacted with an amount of a photoactivator which is effective to cause the residue of the photo-inert moiety to absorb within a wavelength ranging from 300 to 800 nanometers, the residue of the photo-inert moiety is detectable at concentrations of less than 100 parts per million. Methods are also provided which allow for the determination of the concentration of low levels, i.e., less than 100 ppm, of the water-treatment polymer present in an aqueous system.

This invention relates to a process for chemically modifying polysaccharides in a densified fluid. In particular, the modification includes esterification and/or etherification of a starch in supercritical carbon dioxide. The process is advantageous in that it allows for a high degree of substitution without the use of organic solvents or repeated reactions.

For use in microelectronics applications, an improvement to an epoxy resin composition to reduce bleeding of the composition when it is applied to a silicon or metal substrate consists in the addition to the composition of a polyhydroxyl compound having two or three hydroxyl groups, or of a monohydroxyl compound that also contains one or more phenyl groups. The hydroxyl compound is present in the composition in a ratio by weight to the flexibilizing compound of from 1:3 to 1:10.

Latex binders are disclosed which are used to prepare freeze-thaw-stable latex coating compositions which may be free of volatile freeze-thaw/open-time additives. The latex binders are prepared by combining a polymer which is the polymerization product of a polymerizable saccharide monomer, an acrylic monomer and, optionally, a monomer selected from styrenic monomers, ionic monomer and wet adhesion monomers. The latex coating compositions are freeze-thaw stable, even in the total absence of a volatile freeze-thaw additive, and exhibit improved open-time when compared to a latex coating composition which does not contain a volatile freeze-thaw additive. Methods for preparing the freeze-thaw-stable latex coating compositions are also disclosed.

Latex binders and coatings containing polymers derived from

Polymerizable, saccharide-derived monomers are prepared in processes which utilize water as the reaction solvent and which preferably do not utilize a cosolvent. The saccharide monomers are prepared from a saccharide unit, an amine selected from the group consisting of R.sup.3 NH.sub.2, where R.sup.3 is selected from the group consisting of a C.sub.1 -C.sub.18 alkyl group, H or NH.sub.2, and a single, polymerizable, .alpha.-methyl styryl moiety. The saccharide monomers are useful in preparing polymers for use in freeze-thaw stable aqueous-based compositions which do not require conventional freeze-thaw solvents and colorimetrically detectable polymers which are used in treating aqueous systems.

Polymerizable saccharide monomers which contain a single, polymerizable,

A method for epoxidizing olefins is provided wherein an olefin and an oxygenating agent are contacted together in the presence of a manganese complex catalyst having at least one manganese atom coordinated with a nitrogen-containing ligand such that the manganese atom to coordinated nitrogen atom is 1:3 and thereafter isolating the resultant epoxide product. Catalyst compositions are also provided formed from the adsorption of the manganese complex catalyst onto a solvent insoluble support.

Novel fabric conditioning agents which contain either an ester or a NH link between a glyceric carboxyl group and a quaternary ammonium group are described. The compounds based on glyceric acid are both effective fabric conditioners and biodegradable, and may be formulated in any conventional physical form to form a fabric conditioning composition. A method of using the composition is also described.
