US Patent:

6933337, Aug 23, 2005
Filed:

Mar 20, 2003
Appl. No.:

10/393214
Inventors:

Jiamin Lang - Arlington Heights IL, US
Bruce Edward Stanhope - Grayslake IL, US
Thomas Joseph Bohnert - Rochester NH, US
William David Arendt - Libertyville IL, US
International Classification:

C08K005/09
US Classification:

524290, 524291, 524292, 524306, 524308, 524310
Abstract:

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.

US Patent:

7071252, Jul 4, 2006
Filed:

Sep 11, 2003
Appl. No.:

10/660457
Inventors:

Bruce E. Stanhope - Grayslake IL, US
William D. Arendt - Libertyville IL, US
Jiamin Lang - Arlington Heights IL, US
Assignee:

Velsicol Chemical Corporation - Rosemont IL
International Classification:

C08K 5/103
US Classification:

524292, 524569
Abstract:

Monoesters derived from a dihydric alcohol and a carboxylic acid such as benzoic acid are secondary plasticizers for non-aqueous and solventless plastisols containing primary plasticizers that do not contain unreacted alkanol groups.

US Patent:

20030023112, Jan 30, 2003
Filed:

Apr 11, 2001
Appl. No.:

09/832554
Inventors:

Jiamin Lang - Arlington Heights IL, US
Bruce Stanhope - Grayslake IL, US
Thomas Bohnert - Palatine IL, US
William Arendt - Libertyville IL, US
International Classification:

C07C069/76
US Classification:

560/090000
Abstract:

Mixtures of esters produced by reacting an aromatic and an aliphatic monocarboxylic acid with a stoichiometric quantity of a diol are effective plasticizers for polyvinyl chloride and other rigid organic polymers. The freezing point of the mixtures and the efficacy of the present ester mixtures as plasticizers can be varied by adjusting the type and molar ratio of the two types of acids used to prepare the ester mixture.

US Patent:

20030114564, Jun 19, 2003
Filed:

Dec 20, 2000
Appl. No.:

09/742260
Inventors:

Jiamin Lang - Arlington Heights IL, US
Franz Luxem - Palatine IL, US
Bruce Streeter - Crystal Lake IL, US
Bruce Stanhope - Grayslake IL, US
Eric Zimmermann - Algonquin IL, US
Assignee:

Velsicol Chemical Corporation
International Classification:

C08L001/00
US Classification:

524/315000
Abstract:

A portion of the repeating units in polyesters useful as plasticizers for rigid organic polymers are derived from diethylene glycol and at least one dicarboxylic acid. The percentage of these repeating units that can be present in polyesters that are compatible with the organic polymer into which they are incorporated is inversely proportional to the weight average molecular weight of the polyester.
