Patent number: 6933351Abstract: A process for producing polyalkenyl acylating agent, wherein, upon completion of the thermal reaction of a polyalkene and an unsaturated mono- or dicarboxylic acid or anhydride compound, the reaction mixture is allowed to cool to below the reaction temperature, an additional amount of unsaturated mono- or dicarboxylic acid or anhydride compound is added to the cooled reaction mixture, which is then maintained in the reactor for a time period, optionally with agitation. Reducing the temperature of the reaction mixture prior to the introduction of additional unsaturated mono- or dicarboxylic acid or anhydride compound minimizes further reaction between the additional unsaturated mono- or dicarboxylic acid or anhydride compound and any remaining unreacted polyalkene, as well as self-polymerization of the unsaturated mono- or dicarboxylic acid or anhydride compound.Type: GrantFiled: June 20, 2003Date of Patent: August 23, 2005Assignee: Infineum International LimitedInventors: Vincent Jean Marie Michaud, Jeremy Roger Spencer, David Loughlin, David Gordon Birse

Patent number: 6894093Abstract: The present invention describes plastic materials and food additives that are free or substantially free from endocrine disruptive chemicals. The plastic materials may be used in products which are exposed to individuals in which endocrine disruptive activity is particularly disadvantageous, such as baby bottles, baby toys, food containers, medical containers, animal cages and medical products. The food additives may be used in food products that are ingested by individuals in which endocrine disruptive activity is particularly disadvantageous, such as newborns or the physically infirm. The present invention also describes a series of assays which, when performed in combination, provide a novel method for determining the presence of endocrine disruptive activity.Type: GrantFiled: May 10, 2002Date of Patent: May 17, 2005Inventor: George D.

Patent number: 6878780Abstract: Powder coating compositions having reduced volatility and improved processibility compared to conventional powder coatings consist essentially of a copolymer having pendant functionalities or pendant groups capable of reacting with a dicarboxylic acid such as the glycidyl groups of glycidyl acrylate or methacrylate copolymer and a cross-linking effective amount of a dicarboxylic acid. The reaction of the above pendant groups and the dicarboxylic acid cross-links or cures the powder coating after application to a substrate. The dicarboxylic acids according to the invention eliminate the need for a third component which is a flow control agent which improves the processibility of a two-component powder coating. The dicarboxylic acids according to the invention have a sublimation temperature great enough to decrease or prevent their vaporization during the curing of the powder coating and have a melting point low enough to impart improved flow properties to the powder coatings.Type: GrantFiled: June 16, 2003Date of Patent: April 12, 2005Assignee: Cognis CorporationInventors: Jeffrey A. Gates, Michael S. Sharp
