Filed:

Jul 17, 2008

Appl. No.:

12/174996

Inventors:

James E. Schuetz - Sanford MI, US
Thomas W. McCullough - Lake Jackson TX, US
Neil Anderson - Calumet MI, US
Justin LaCosse - Calumet MI, US
Thomas D. Wood - Houghton MI, US

Assignee:

CENTURY, INC. - Traverse City MI

International Classification:

B01D 71/00

US Classification:

264 79

Abstract:

A method of controlling evaporation of a fluid, such as water, in an article includes the step of encapsulating the article with a film such that the fluid is prevented from evaporating from the article. The method further includes the step of heating the article encapsulated with the film to a first desired temperature for a first period of time while preventing the fluid from evaporating from the article. The method also includes the step of removing the film from the article after heating the article to the first desired temperature for the first period of time and, after the step of removing the film the article, the method includes the step of further heating the article to a second desired temperature for a second period of time while the fluid freely evaporates from the article.

Gerald F. Billovits - Midland MI
Scott A. Tipler - Midland MI
Thomas W. McCullough - Lake Jackson TX

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

C08F 600
C08F 1204

US Classification:

528503

Abstract:

The present invention is an improvement in a solid state devolatilization finishing process for a wet feed material of syndiotactic vinyl aromatic polymer containing volatiles, including at least one vinyl aromatic monomer, wherein the improvement comprises: rapidly heating the wet feed material, such that the temperature of the wet feed material is increased at a rate of at least 10. degree. C. /min. , to a temperature between about 150. degree. C. and the melting point temperature of the syndiotactic vinyl aromatic polymer, while concurrently removing evolved volatiles.
