Patents by Inventor Terry Dunn

Terry Dunn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Semi-crystalline polymers stabilized for irradiation sterilization
    Patent number: 4467065
    Abstract: Semi-crystalline polymer having a narrow molecular weight distribution and having incorporated therein a non-crystalline mobilizing additive which increases the free volume of the polymer, with such a combination preventing embrittlement of the polymer during and subsequent to irradiation sterilization.
    Type: Grant
    Filed: January 8, 1981
    Date of Patent: August 21, 1984
    Assignee: Becton Dickinson and Company
    Inventors: Joel Williams, Terry Dunn, Vivian Stannett

  • Irradiation sterilization of semi-crystalline polymers
    Patent number: 4110185
    Abstract: An article of a semi-crystalline polymer such as polypropylene, is sterilized by high energy irradiation, with the polymer containing a non-crystalline mobilizing additive which increases the free volume of the polymer, to thereby prevent embrittlement of the polymer during and subsequent to the irradiation. The additive has a density of from 0.6 to 1.9 g/cm.sup.3 and a molecular weight from 100 to 10,000 g/mole.
    Type: Grant
