Patent number: 7307183Abstract: A method for preparing tetrabromobenzoate ester from a tetrabromophthalic anhydride including the steps of reacting the tetrabromophthalic anhydride with a catalyst and an alcohol at a temperature that favors partial esterification over complete esterification of the tetrabromophthalic anhydride to form a tetrabromophthalate half-ester reaction mixture; and feeding the half-ester reaction mixture to at least one reactor having and maintaining a temperature that favors decarboxylation over esterification to produce a tetrabromobenzoate ester-containing product. The temperature favoring partial esterification of the tetrabromophthalic anhydride is between about 70° C. and 130° C. The temperature favoring decarboxylation over esterification is between about 190° C. and 205° C. The tetrabromobenzoate ester-containing product comprises at least about 85% tetrabromobenzoate ester. The at least one reactor may include two or more reactors connected to one another in series.Type: GrantFiled: July 29, 2003Date of Patent: December 11, 2007Assignee: Great Lakes Chemical CorporationInventors: David W. Bartley, James D. Siebecker, Stephen B. Falloon

Patent number: 7285587Abstract: Flame retardant polyester compositions suitable for calendering may be prepared from polyesters having crystallization half time of at least 5 minutes, a plasticizer, a phosphorus-containing flame retardant miscible with the plasticized polyester, and an additive effective to prevent sticking of the polyester to the calendar rolls. Also disclosed are processes for flame retardant films or sheets by calendering the above compositions and the flame retardant films or sheets produced therefrom. These films and sheets have excellent appearance, flexibility, and flame retardancy, and can be used in a wide range of decorative and packaging applications.Type: GrantFiled: November 12, 2003Date of Patent: October 23, 2007Assignee: Eastman Chemical CompanyInventors: Marc Alan Strand, Rodney Layne Piner

Patent number: 6933337Abstract: Mixtures of esters produced by reacting a mixture of aromatic and aliphatic monocarboxylic acids with a diol containing from 2 to 12 carbon atoms are effective plasticizers for plastisols containing dispersion grade polymers of vinyl chloride. The freezing point of the present ester mixtures and their efficacy as plasticizers can be varied by adjusting the type and relative concentration of the aliphatic acid used to prepare the plasticizer. The ester mixtures can also be used as plasticizers for other organic polymers.Type: GrantFiled: March 20, 2003Date of Patent: August 23, 2005Inventors: Jiamin Lang, Bruce Edward Stanhope, Thomas Joseph Bohnert, William David Arendt
