  • Process for crosslinking of acrylic ester copolymers
    Patent number: 6720390
    Abstract: Disclosed is a process for crosslinking copolymers of 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: April 5, 2002
    Date of Patent: April 13, 2004
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: Gordon Mark Cohen, Jerald Rice Harrell, Edward Johson Deyrup
  • Grafting of polyolefins
    Patent number: 6559235
    Abstract: Porous polyolefins are especially efficiently free-radically grafted using (fluorinated alkyl)olefins, vinylsilanes or certain carboxylic acids or their esters as the grafting molecules. The use of a solvent to swell the porous polyolefin is sometimes advantageous.
