  • Cellulosic composition
    Patent number: 7628888
    Abstract: A composition includes at least one hydrophilic polymer containing primary (—NH2) and/or secondary (—NHR) amine groups and at least one saccharide containing a reducible function. A method of increasing the strength of paper includes the step of contacting the paper with a composition comprising (i) at least one hydrophilic polymer containing at least two groups which are independently the same or different a primary amine group or a secondary amine group and at least one saccharide containing a reducible function. A hydrogel composition is formed from a mixture of at least one hydrophilic polymer containing at least two groups which are independently the same or different a primary amine group or a secondary amine group and at least one saccharide containing a reducible function.

  • N-vinyl-n-acyl urea resins
    Patent number: 5569725
    Abstract: A class of unsaturated resins which are suitable for use in radiation curable coatings has been developed. The resins comprise N-vinyl-N-acyl oligomers made by reacting a secondary N-vinylamide with a polyisocyanate monomer which is reacted with at least one mono- or polyhydric alcohol to form a urethane linkage.

  • Regeneration of metallo-organic catalyst for carbon dioxide-epoxide copolymerization
    Patent number: 4960862
    Abstract: A process is provided for regenerating metallo-organic catalyst used in copolymerizing carbon dioxide with epoxides to form poly(alkylene carbonates). The catalyst is a polyvalent metal dicarboxylate and the regeneration procedure involves contacting spent or deactivated catalyst with dicarboxylic acid, preferably in a slurry. In one aspect the copolymerization is carried out and catalyst is separated from the polymerization mixture, reactivated with the dicarboxylic acid, such as glutaric or adipic acid, and reused in copolymerization to form poly(alkylene carbonate).
