  • Patent number: 6784397
    Abstract: The present invention is directed to a release composition for molds and formers used in the production of natural and synthetic latex articles. The release coating contains a water-borne, high Tg polymer formed from at least one hydrophobic monomer and at least one hydrophilic monomer, where the Tg of the polymer is at least −10° C. One advantage of the release composition is that it is compatible with a coagulant solution used in the formation of latex gloves. Articles formed using the release coating have good anti-blocking properties.

  • Patent number: 6692840
    Abstract: The present invention is directed to the use of a polymer coating composition having a dispersant, microbeads and a high Tg polymer with a Tg of greater than −10° C. for the inner coating on natural and synthetic rubber articles, particularly for latex gloves. The coating for rubber articles, provides an inner surface coating that reduces friction between the latex and the hand to allow convenient donning. They are deliverable from aqueous solution.

  • Patent number: 6540876
    Abstract: This invention pertains to the use of compounds containing amide or imide type functional groups to increase the rate of nitroxide mediated oxidation of alcohols, particularly primary and secondary alcohols. While suitable for oxidation of alcohol groups on a variety of substrates, it is particularly useful to oxidize cellulose, cellulose pulp or cellulose fiber such that it is commercially compatible with the traditional paper making process. Such co-catalysts may be used to increase the absolute amount of aldehyde groups on cellulose, cellulose pulp or cellulose fiber, thereby further increasing the inherent wet strength, temporary wet strength, and dry strength of paper made with such cellulose, cellulose pulp or cellulose fiber.
