Publication number: 20030149150Abstract: Compounds and compositions comprising specific metal salts of hexahydrophthalic acid (HHPA) in order to provide highly desirable properties within thermoplastic articles are provided. The inventive HHPA derivatives are useful as nucleating and/or clarifying agents for such thermoplastics, are practical and easy to handle. Such compounds provide excellent crystallization temperatures, stiffness, and acid scavenger compatibility within target polyolefins. Also, such compounds exhibit very low hygroscopicity and therefore excellent shelf stability as powdered or granular formulations. Thermoplastic additive compositions and methods of producing polymers with such compounds are also contemplated within this invention.Type: ApplicationFiled: December 28, 2002Publication date: August 7, 2003Inventors: Darin L. Dotson, X. Edward Zhao

Patent number: 6541662Abstract: A process for producing a hydrogenation product of aromatic carboxylic acid which comprises continuously producing the hydrogenation product of aromatic carboxylic acid by hydrogenating an aromatic carboxylic acid having a melting point of 250° C. or higher in a solvent in the presence of a solid catalyst, wherein the hydrogenation is conducted in a condition such that substantially the entire amount of the aromatic carboxylic acid of a raw material is dissolved in the solvent by recycling a portion of a reaction liquid taken out of a reactor into the reactor. An aromatic carboxylic acid having a high melting point and hardly soluble in solvents can be hydrogenated at a suitable reaction temperature in accordance with a continuous process without using a great amount of a solvent and the reaction product of the object compound can be produced very efficiently.Type: GrantFiled: December 19, 2001Date of Patent: April 1, 2003Assignee: Mitsubishi Gas Chemical Company, Inc.Inventors: Hiroshi Machida, Ko Kedo, Fumiya Zaima

Patent number: 6489504Abstract: A malic acid or oxalacetic acid derivative is represented by the following formula (1): wherein ring Z is an alicyclic carbon ring; each of Ra and Rb is independently a hydrogen atom, a metal atom, or an organic group; and Y is a hydroxyl group or an oxygen atom, where ring Z is a bridged carbon ring or a monocyclic carbon ring having eight or more members when Y is an oxygen atom. The alicyclic carbon ring includes, for example, cyclooctane ring and adamantane ring. This compound is a novel malic acid derivative having an alicyclic group bonded to a carbon atom at the 3-position, or a novel oxalacetic acid derivative having a specific alicyclic group bonded to a carbon atom at the 3-position.Type: GrantFiled: March 9, 2001Date of Patent: December 3, 2002Assignee: Daicel Chemical Industries, Ltd.Inventors: Yasutaka Ishii, Tatsuya Nakano
