  • Process for crosslinking of ethylene/acrylic ester copolymers
    Patent number: 6803424
    Abstract: Disclosed is a process for crosslinking copolymers of ethylene and acrylic esters by converting some of the ester groups to ester or amide groups which contain unsaturation, and then sulfur or peroxide curing the resulting polymers. The resulting crosslinked polymers often have excellent vulcanizate properties, and are useful especially in elastomeric form as seals and gasket.
    Type: Grant
    Filed: July 25, 2002
    Date of Patent: October 12, 2004
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: Herbert Vernon Bendler, Gordon Mark Cohen, Clara Young Lin, Robert Louis Dawson, Jerald Rice Harrell, Sampson Chun Fai Lee

  • Process for preparing polyamides
    Patent number: 6069228
    Abstract: Disclosed is a process for the preparation of polyamide polymers via prepolymer formation in a reactor system comprising a reactor, flasher and separator, crystallization of the prepolymer under controlled temperature conditions and the subsequent conversion of these crystallized prepolymers to high molecular weight polymer.
