Ethylene/Alkyl Acrylate Copolymers, Compounds And Vulcanizates Thereof
US Patent:
7521503, Apr 21, 2009
Filed:
Jun 30, 2006
Appl. No.:
11/478949
Inventors:
Yun-Tai Wu - Bryn Mawr PA, US
Mark Aaron Stewart - Wilmington DE, US
Yi Ye - The Woodlands TX, US

Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08L 31/00
C08F 20/10
C08F 210/00
C08F 20/10
C08F 210/00
US Classification:
524556, 526328, 526348
Abstract:
Disclosed are copolymers derived from ethylene and at least two different alkyl acrylate comonomers, with or without an acid cure site-containing comonomer. The copolymers can be derived from (a) from 10 to 50 weight % of ethylene; (b) 20 to 30 weight % of a first alkyl acrylate having from 1 to 4 carbons in the alkyl group; from 35 to 45 weight % of a second different alkyl acrylate having from 1 to 4 carbons in the alkyl group; and (d) from 0 to 5 weight % of a 1,4-butene-dioic acid moiety, or anhydride or monoalkyl ester thereof; the remainder being ethylene: wherein the copolymer has a number average molecular weight (M) above 40,000. Also disclosed are compounded compositions comprising these copolymers and cured compositions (i. e. , vulcanizates) as well as rubber articles formed from these compounded compositions, such as constant velocity joint boots and shaft boots, hoses, dampers, seals and gaskets. These copolymers provide improved dynamic fatigue resistance of cured compounds while maintaining an expanded operating temperature range and oil resistance.

Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08F 220/10
US Classification:
526329, 524556, 525227, 525228
Abstract:
Disclosed are copolymers derived from ethylene and an alkyl acrylate comonomer wherein the copolymer has a number average molecular weight (M) above 40,000. This invention also provides compounded compositions and cured compositions (i. e. , vulcanizates) comprising these copolymers. The copolymers provide improved dynamic fatigue resistance of the vulcanizates. Also disclosed are articles comprising the copolymers, such as tubing, hoses, dampers, seals and gaskets.
Ethylene/Methyl Acrylate/Cure Site Copolymers And Compounds And Vulcanizates Thereof
US Patent:
7608675, Oct 27, 2009
Filed:
Jun 30, 2006
Appl. No.:
11/479039
Inventors:

Assignee:
E.I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08F 220/10
US Classification:
526329, 526328, 526348, 524556
Abstract:
Disclosed are copolymers derived from copolymerization of from about 50 to about 70 weight % of methyl acrylate; from about 0. 5 to about 5 weight % of 1,4-butene-dioic acid moieties, or anhydrides or monoalkyl esters thereof; the remainder being ethylene, wherein the copolymer has a number average molecular weight from about 40,000 to about 65,000 and a melt index from about 1 to about 6 g/10 minutes. Also disclosed are compounded compositions comprising these copolymers, and cured compositions (i. e. , vulcanizates) as well as rubber articles formed from these compounded compositions, such as hoses, dampers, boots, seals, and gaskets for automotive and nonautomotive applications. Blends of other polymers with these copolymers are also disclosed.
