International Classification:
C08L 2308
US Classification:
525186, 525404, 525450
Abstract:

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.

Filed:
Jul 10, 1992
Appl. No.:
7/912963

C08F 806
C08F 626
C08F 626
US Classification:
525387
Abstract:
The viscosity of copolymers of a) ethylene, b) C. sub. 1 -C. sub. 8 acrylates, C. sub. 1 -C. sub. 8 methacrylates, or vinyl esters of C. sub. 1 -C. sub. 8 carboxylic acids, and c) at least one alpha, beta-unsaturated carboxylic acid of 3-12 carbon atoms selected from the group consisting of monocarboxylic acids, dicarboxylic acids, and monoesters of dicarboxylic acids is increased, while maintaining gel content at a level of less than 3%, by treatment with a mixture of an organic peroxide and a chromium (III) salt.
Ethylene Copolymer Compositions
US Patent:
4839412, Jun 13, 1989
Filed:
Sep 1, 1987
Appl. No.:
7/093561
Inventors:

Assignee:
E. I. Du Pont De Nemours and Company - Wilmington DE
International Classification:
C08K 310
US Classification:
524436
Abstract:
Certain ethylene copolymers that contain an ethylene/anhydride graft copolymer and a magnesium hydroxide or aluminum trihydrate flame and smoke retardant have a good balance of strength and flame and smoke retardant properties. The compositions preferably also contain polyethylene, and/or ionomeric ethylene copolymer and/or an ethylene/propylene elastomer.
