  • Patent number: 10662347
    Abstract: Methods for preparing copolymeric emulsions from at least one water soluble monomer and at least one water insoluble monomer are disclosed herein. In some embodiments, one or more surfactants and stabilizers may be used. In some embodiments, the monomers used in the process include, by total monomer weight, at least 50% water soluble monomers and at least 10% water insoluble monomers. Copolymer emulsions formed from the reaction product of at least one water soluble monomer and at least one water insoluble monomer are also disclosed along with articles coated with such emulsions and coating formulations made from such emulsions as well as methods for the manufacture and coating of such articles.

  • Patent number: 10125239
    Abstract: The present invention generally relates to vulcanization compositions used to vulcanize elastomeric articles, where the vulcanization compositions have reduced allergenic potential as compared to elastomeric articles formed using vulcanization compositions having non-fugitive accelerators. The present invention also relates to elastomeric articles formed using the vulcanization compositions. The invention further relates to methods for making a reduced-allergenicity vulcanization composition, and to methods for using the vulcanization compositions to vulcanize elastomeric articles.

  • Publication number: 20080020023
    Abstract: The invention described herein relates to a therapeutic, moisturizing coating composition for elastomeric articles which is applied directly onto the skin-contacting surface of the article as part of the manufacturing process. The coating composition is thermally stable and subsequently transfers when in contact with a skin surface to convert into a liquid “lotion” form during wearing of the article. The coating composition provides therapeutic benefits to the wearer's skin as a result of wearing the article, such as improved skin moisturization, softness of feel, improved skin elasticity and firmness, and reduced redness and irritation. The invention is particularly useful in medical gloves, including examination and surgical gloves.
