Compositions Of Elastomeric Ethylene/(Meth)Acrylic (Acid) Ester Copolymer And Polylactone Or Polyether
US Patent:
6528586, Mar 4, 2003
Filed:
Jun 20, 2001

Jerald Rice Harrell - Wilmington DE, 19803
Sampson Chun-Fai Lee - Scarborough, Ontario, M1K 1C6, CA
David John Mitchell - Kingston, Ontario, K7L 5A5, CA
International Classification:
C08L 2308
US Classification:
525186, 525404, 525450
Abstract:
Disclosed are compositions of ethylene and (meth)acrylic acid and ester elastomeric copolymers or of (meth)acrylic ester elastomeric copolymers with polylactones and certain polyethers.
Process For Crosslinking Of Acrylic Ester Copolymers
US Patent:
6720390, Apr 13, 2004
Filed:
Apr 5, 2002
Appl. No.:
10/117380
Inventors:
Gordon Mark Cohen - Wynnewood PA

Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08F12010
US Classification:
5253306, 5253286, 5253292, 5253295, 5253298, 5253303, 526318, 526319, 526324, 5263297, 526330, 526331
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.
