Patent number: 6831115Abstract: 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: February 6, 2002Date of Patent: December 14, 2004Assignee: Eastman Chemical CompanyInventors: Kevin Alan Williams, Michael Bellas, Charlie Carroll Freeman, Jr., Lisa Kay Templeton

Patent number: 6709717Abstract: To produce a composite building unit having a polymer-cladded surface, a polymerizable resin binder and a blend of filler particles are combined to provide a resin binder/filler mixture which is deposited in a mold. A concrete substrate is then positioned in the mold with a face surface contacting a transition layer comprising a lightly filled resin binder/filler layer portion of the deposited mixture overlying a highly filled resin binder/filler layer portion of the deposited mixture. The resin binder in the transition layer migrates into pockets and pores in the substrate face surface to create mechanical locks when the resin binder is cured. These locks, in addition to chemical bonding, serve to permanently affix the cured resin binder as a surface cladding to the substrate. Initiators may be added to the resin binder to promote thermal and/or UV radiation cures thereof.Type: GrantFiled: March 15, 2002Date of Patent: March 23, 2004Assignee: Margrace Enterprises, Inc.Inventor: John N.

Patent number: 5686518Abstract: An essentially stable monomer miniemulsion characterized by small monomer droplet size is prepared and is then polymerized to a polymer latex under free radical polymerization conditions. The monomer miniemulsions herein include, in addition to water, a surfactant, and a monomer or mixture thereof, one or more polymers which function as a polymeric co-surfactant. The monomer miniemulsions are characterized by average monomer droplet size of 10 to 500 nanometers, preferably 80 to 150 nanometers. The amount of polymer added as a co-surfactant is about 0.5 to about 5 percent by weight based on monomer weight. The monomer emulsion may contain either a single monomer or a monomer mixture. The monomer emulsion is polymerized under conventional emulsion polymerization conditions yielding a polymer latex having an average polymer particle size of 10 to 500 nanometers, preferably 80 to 150 nanometers, and a narrow particle size distribution, i.e., a polydispersity index of about 1.05 to about 1.40.Type: GrantFiled: January 3, 1995Date of Patent: November 11, 1997Assignee: Georgia TechInventors: Kevin J. Fontenot, F. Joseph Schork, Jay L. Reimers

Patent number: 5604290Abstract: A self-crosslinking composition contains: (a) an oil having an unsaturated fatty acid or an ester of an unsaturated fatty acid as one of its components, (b) a drier, and (c) a polymer or an elastomer that is capable of crosslinking in the absence of a peroxide. A forming (such as a floor tile, a linoleum long floor material, a wall material and a water-proof sheet) may be manufactured by forming and curing the self crosslinking composition and then adding a filler. Since the self-crosslinking composition is capable of crosslinking without using peroxide, the crosslinking reaction is easily conducted without using special equipment to reject air. The composition has a number of advantages over crosslinking methods that use peroxide, including decreased scorch generation, decreased permanent compressive strain, and superior heat resistance and anti-aging resistance. The composition is free from pollution of sulfur and metal and generates no harmful gas during waste incineration.Type: GrantFiled: April 14, 1995Date of Patent: February 18, 1997Assignee: Tajima IncorporatedInventors: Satoru Aikawa, Eiichi Tajima
