Patent number: 6887940Abstract: A compatible blend of an engineering thermoplastic such as a polyamide and an olefin polymer material is prepared by (1) making an oxidized olefin polymer material containing carboxylic acid groups or derivatives thereof, (2) extruding a mixture of (a) the oxidized olefin polymer material from step (1), (b) an engineering thermoplastic, (c) optionally, an inorganic base, and (d) optionally, a non-oxidized olefin polymer material, and (3) recovering a blend of the engineering thermoplastic, the oxidized olefin polymer material or an ionomer thereof, which acts as a compatibilizer, and, optionally, the non-oxidized olefin polymer material. The oxidized olefin polymer material can be made by treating the olefin polymer material with an organic peroxide initiator while adding a controlled amount of oxygen.Type: GrantFiled: November 27, 2002Date of Patent: May 3, 2005Assignee: Basell Poliolefine Italia S.p.A.Inventors: Vu A.

Patent number: 6828385Abstract: A process has now been discovered that permits the simultaneous crosslinking and derivation of an, optionally hydrogenated, polymer whose backbone is composed of a conjugated diene, an unsaturated nitrile and an unsaturated carboxylic acid in the presence of a coupling/condensing agent. This permits the preparation of a novel polymeric material that is an optionally hydrogenated polymer of a conjugated diene, an unsaturated nitrile and a derived unsaturated acid. It has also been found that this novel polymeric material has unexpected and valuable properties.Type: GrantFiled: October 8, 2002Date of Patent: December 7, 2004Assignee: Bayer Inc.Inventors: Janet N. Gamlin, Sharon X. Guo

Patent number: 6821632Abstract: In a composite of vulcanizable rubber or rubber-like composition with one or more metal reinforcement elements embedded therein, the metal reinforcement element is coated with a polymer or non-cured rubber composition compatible with and co-polymerizable, co-vulcanizable or crosslinkable with said vulcanizable ruber composition to be reinforced, and additionally bearing functional groups either covalently bonding to the metal surface of said reinforcement element or forming covalent bonds with the outward directed first functional groups of a mono- or multimolecular layer of a bifunctional adhesion promoter intercalated between said metal and said coating and bound to said metal by its second functional groups. A cured rubber or rubber-like product, for instance a pneumatic tire, is obtained by vulcanization of such a composite.Type: GrantFiled: April 13, 2001Date of Patent: November 23, 2004Assignee: Continental AktiengesellschaftInventors: Andreas Topp, Bernd Kaiser, Richard Michalitsch, Francis Garnier, Philippe Lang

Patent number: 6753382Abstract: The present invention relates to a method of acrylonitrile-butadiene-styrene (ABS) rubber latex, and the acrylonitrile-butadiene-styrene (ABS) latex is prepared by graft-polymerizing butadiene rubber with the monomers of acrlylonitrile and styrene through emulsion-polymerization, so that the ABS rubber latex of the present invention has high solid content. The method of ABS rubber latex of the present invention comprises the step of emulsion-polymerizing i) polybutadiene rubber latex; ii) aromatic vinyl compound; and iii) vinyl cyanide with the addition of a reactive emulsifier. According to the method of the present invention, the ABS rubber latex has high solid content due to a decrease in the amount of coagulated materials and film, which formed on the rubber latex during polymerization, and an increase in the production volume.Type: GrantFiled: July 22, 2002Date of Patent: June 22, 2004Assignee: LG Chemical Co., Ltd.Inventors: Geon-Soo Kim, Chan-Hong Lee, Byung-Tae Yang, Joo-Byung Chai
