Publication number: 20120040195Abstract: The present invention provides solvent- and water-based primer compositions that include at least one carboxylated polyolefin that has been modified with one or more polyfunctional alcohols. The carboxylated polyolefins are obtained by the reaction of polyolefins with at least one of unsaturated carboxylic esters, unsaturated carboxylic acids, unsaturated carboxylic anhydrides, acrylic monomers, and mixtures thereof. The carboxylated polyolefins are then further modified by reaction with one or more polyfunctional alcohols. These polyfunctional alcohol-modified polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines or inorganic bases, thereby rendering the polyfunctional alcohol-modified polyolefins water-dispersible. These primer compositions are useful for significantly improving the adhesion of paints, adhesives, and inks to various plastic and metal substrates.Type: ApplicationFiled: October 20, 2011Publication date: February 16, 2012Applicant: EASTMAN CHEMICAL COMPANYInventors: Kevin Alan Williams, Robert Lee Eagan, Lisa Kay Templeton, Richard Leon McConnell

Patent number: 8058355Abstract: The present invention provides solvent- and water-based primer compositions that include at least one chlorinated carboxylated polyolefin that has been modified with one or more polyfunctional alcohols. The chlorinated carboxylated polyolefins are obtained by the reaction of polyolefins with at least one of unsaturated carboxylic esters, unsaturated carboxylic acids, unsaturated carboxylic anhydrides, acrylic monomers, and mixtures thereof then chlorinated. The chlorinated carboxylated polyolefins are then further modified by reaction with one or more polyfunctional alcohols. These polyfunctional alcohol-modified chlorinated carboxylated polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines or inorganic bases, thereby rendering the polyfunctional alcohol-modified chlorinated carboxylated polyolefins water-dispersible.Type: GrantFiled: August 31, 2005Date of Patent: November 15, 2011Assignee: Eastman Chemical CompanyInventors: Robert Lee Eagan, Kevin Alan Williams, Allen Morgan Cheek

Patent number: 7388039Abstract: Modified polyolefins are produced by reacting a functionalized polyolefin with one or more ethylenically unsaturated compounds having a functional group reactive with the functional group on the polyolefin. These modified polyolefins may then polymerize in the presence of a photoinitiator upon exposure to ultraviolet radiation and also have the capability of copolymerizing in the presence of a photoinitiator with other ethylenically unsaturated crosslinking agents upon exposure to ultraviolet radiation. These modified polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines, and therefore may be rendered water-dispersible. The modified polyolefins of the present invention significantly improve the adhesion of paints, inks, and adhesives to various plastic and metal substrates.Type: GrantFiled: July 14, 2004Date of Patent: June 17, 2008Assignee: Eastman Chemical CompanyInventors: Kevin Alan Williams, Michael Bellas, Charlie Carroll Freeman, Jr., Lisa Kay Templeton

Patent number: 6657075Abstract: Disclosed is a continuous process for the production of tertiary butyl esters by the reaction of a ketene and tertiary butyl alcohol containing a finite concentration of water. The process may be carried out in an absorber reactor with continuous recovery and purification of products by distillation. This process provides high-purity tertiary butyl acetate without the production of unwanted by-products found in many strong acid catalyzed processes.Type: GrantFiled: March 27, 2002Date of Patent: December 2, 2003Assignee: Eastman Chemical CompanyInventors: Kevin Alan Williams, Steven Leroy Cook, Phillip Wayne Turner

Publication number: 20020010257Abstract: The invention relates to solvent-based primer compositions containing 0.5 to 40 weight percent of a modified polyolefin and a solvent selected from the group consisting of ester solvents, ketone solvents, aliphatic solvents, aromatic solvents and mixtures thereof. The modified polyolefin is formed from an amorphous polyolefin selected from polypropylene and a propylene copolymer or a propylene terpolymer or an ethylene copolymer or terpolymer. Preferably the polyolefin is a polypropylene copolymer or terpolymer containing about 1 to about 99 mole percent ethylene, 1-butene, 1-pentene, and 1-hexene. The amorphous polyolefin has a number average molecular weight ranging from about 1,000 to 15,000 and is chemically modified with one or more unsaturated carboxylic acids selected from the group consisting of acids, esters and anhydrides. These primers are useful for significantly improving the adhesion of paints to polyolefin surfaces.Type: ApplicationFiled: October 5, 2001Publication date: January 24, 2002Applicant: Eastman Chemical CompanyInventors: Lisa Kay Templeton, Kevin Alan Williams, Richard Leon McConnell, Michael Alan Callahan
