Patent number: 6287992Abstract: A polymer composite comprising an epoxy vinyl ester resin or unsaturated polyester matrix having dispersed therein particles derived from a multilayered inorganic material which possesses organophilic properties. The dispersion of the multilayered inorganic material in the polymer matrix is such that an increase in the average interlayer spacing of the layered inorganic material occurs to a significant extent resulting in the formation of a nanocomposite.Type: GrantFiled: April 20, 1998Date of Patent: September 11, 2001Assignee: The Dow Chemical CompanyInventors: Christine A.

Patent number: 6156806Abstract: The present invention is a composition comprising either: a) a high internal phase ratio emulsion having water as a continuous phase and a thermoplastic hydroxy-functional polyether as a disperse phase; or b) a stable aqueous dispersion of the thermoplastic hydroxy-functional polyether. The composition of the present invention addresses a need in the art by providing a thermoplastic coating that exhibits an excellent barrier to oxygen and carbon dioxide, but which barrier properties are not adversely affected by contact with water. The composition is particularly useful in the paper packaging industry where biodegradability and resistance to spoilage of food is desirable.Type: GrantFiled: August 26, 1998Date of Patent: December 5, 2000Assignee: The Dow Chemical CompanyInventors: Christian Piechocki, James E. Pate, Michael N. Mang, Jerry E. White, Dale C. Schmidt

Patent number: 6156835Abstract: A polymer composite comprising a hydroxy-phenoxyether or polyester polymer matrix having dispersed therein layers of an inorganic material derived from a multilayered inorganic material having organophilic properties. The dispersion of the multilayered inorganic material in the polymer matrix is such that an increase in the average interlayer spacing of the layered inorganic material occurs. This increase in interlayer spacing occurs to a significant extent resulting in the formation of a nanocomposite. The polymers are preferably derived from a diglycidyl ether or ester or an epihalohydrin and a dinucleophile such as a dicarboxylic acid, a difunctional amine, a bisphenol or a sulfonamide. As the organophilic inorganic material clay minerals modified with organic ammonium compounds are used.Type: GrantFiled: August 5, 1998Date of Patent: December 5, 2000Assignee: The Dow Chemical CompanyInventors: Kenneth W. Anderson, Chai-Jing Chou, Jerry E. White, Christine A. Polansky

Patent number: 6054510Abstract: Compositions of the invention include a hydroxy-functional polyester and a natural polymer. Articles can be made from such a composition so as to have sufficiently strong tensile strengths as to form disposable utensils or to have sufficient stretchability so as to form thin wrap films. However, the compositions are more environmentally friendly than commodity plastics such as polyethylene or polystyrene. Granular starches derived from a grain, a root, a legume, or mixtures thereof, are particularly preferred as the natural polymers for inclusion in the compositions.Type: GrantFiled: September 10, 1998Date of Patent: April 25, 2000Assignees: The United States of America as represented by the Secretary of the Agriculture, Biotechnology Research and Development CorporationInventors: Julious L. Willett, William M. Doane, Wayne Xu, Michael N. Mang, Jerry E. White

Patent number: 6051294Abstract: Hydroxy-functional polyethers having a "cardo" diphenylene group in their backbones are prepared by contacting at least one dinucleophilic monomer with at least one dtglycidyl ether of a cardo bisphenol, such as bis(hydroxyphenyl)fluorene, phenolphthalein, or phenolphthalimidine or a substituted cardo bisphenol, such as a substituted bis(hydroxyphenyl)fluorene, a substituted phenolphthalein or a substituted phenolphthalimidine, under conditions sufficient to cause the nucleophillo moieties of the dinucleophilic monomer to react with epoxy moieties to form a polymer backbone containing pendant hydroxy moieties and ether, imino, amino, sulfonamido or ester linkages. These polyethers possess a combination of high barrier to oxygen transmission (i.e., oxygen transmission rate less than 10.0 cm.sup.3 -mil/100 in.sup.2 -atm-day to oxygen) and high heat resistance (i.e., Tg above 120.degree.
