  • Biomedical electrode
    Patent number: 4273135
    Abstract: An essentially dry, disposable biomedical electrode is disclosed having an improved electrically-conductive material at the interface between the electrode and the skin. The conductive material consists essentially of a cohesive, conformable, nonionic hydrophilic synthetic polymer.
    Type: Grant
    Filed: September 8, 1978
    Date of Patent: June 16, 1981
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Franklin C. Larimore, Steven M. Heilmann
  • Acrylic functional aminocarboxylic acids and derivatives as components of pressure sensitive adhesives
    Patent number: 4172934
    Abstract: High performance thermoplastic pressure sensitive adhesives are prepared by the copolymerization of N-(meth)-acryloylamino acids and acid derivatives with long-chained alkyl acrylates. The copolymers can be formulated into tapes that possess an excellent threefold balance of the necessary tape properties of tack, adhesion and cohesion.
    Type: Grant
    Filed: November 1, 1978
    Date of Patent: October 30, 1979
    Assignee: Minnesota Mining and Manufacturing Company

  • Pressure-sensitive adhesive tape employing moisture resistant acrylate-base copolymer adhesive
    Patent number: 4074004
    Abstract: Normally tacky and pressure-sensitive adhesive tapes, labels, etc. which, when adhered to dry fibrous webs, remain firmly attached when the web and adhesive are thereafter exposed to moist conditions. These performance characteristics, which are not found when conventional pressure-sensitive adhesives are used, result from employing acrylate-based copolymer adhesives made from specific monomers and having inherent viscosities related to the monomers employed.
