Process For Crosslinking Of Ethylene/Acrylic Ester Copolymers
US Patent:
6803424, Oct 12, 2004
Filed:
Jul 25, 2002
Appl. No.:
10/182355

Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08F11804
US Classification:
5253261, 526318, 5263184, 526319, 5263232, 526324
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.
Simultaneously Chlorinating And Grafting A Cure Site Onto Polyethylene In An Aqueous Suspension
US Patent:
4477633, Oct 16, 1984
Filed:
Dec 15, 1983
Appl. No.:
6/561523
Inventors:
Robert L. Dawson - Wilmington DE
Assignee:
E. I. DuPont de Nemours and Company - Wilmington DE
International Classification:
C08F 846
US Classification:
525292
Abstract:
A chlorinated polyethylene elastomer is made by mixing polyethylene with water to form an aqueous suspension of the polyethylene and simultaneously chlorinating and grafting a cure site on the polyethylene by mixing and heating the aqueous suspension containing a free radical initiator, gaseous chlorine and about 0. 1-1. 5 moles per kg of polyethylene of an alkyl or alkylaryl monester of butenedioic acid having the formulas ##STR1## or mixtures thereof, where R. sub. 1 is an alkyl or alkylaryl group having from about 8-20 carbon atoms and R. sub. 2 and R. sub. 3 are hydrogen, chlorine or an alkyl group having from about 1-4 carbon atoms.
Thermoplastic Polymer Alloy Composition
US Patent:
5206294, Apr 27, 1993
Filed:
Nov 6, 1991
Appl. No.:
7/788622
Inventors:
Robert L. Dawson - Wilmington DE
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08L 2308, C08L 2312, C08L 3302, C08L 3314
US Classification:
525196
Abstract:
Thermoplastic polymer alloy compositions are provided consisting of a blend of polypropylene, ethylene copolymer ionomer resin, ethylene/glycidyl acrylate or methacrylate copolymer, and uncrosslinked ethylene propylene rubber. The compositions are particularly useful in applications where a wide range of temperature and abrasive conditions are encountered.
