Patent number: 6960272Abstract: A method for bonding a material to a first substrate surface that includes providing a catalyst at the first substrate surface and then contacting that surface with a material that undergoes a metathesis reaction to bond the material to the first substrate surface. There are two embodiments of this method—a coating process and an adhesive process. In the coating embodiment, the metathesizable material is contacted with the catalyst on the substrate surface so that it undergoes metathesis polymerization to form the coating. The adhesive process includes (a) providing a catalyst at the first substrate surface, (b) providing a metathesizable material between the first substrate surface and the second substrate surface, and (c) contacting the catalyst on the first substrate surface with the metathesizable material so that the metathesizable material undergoes a metathesis reaction and bonds the first substrate surface to the second substrate surface.Type: GrantFiled: November 13, 2000Date of Patent: November 1, 2005Assignee: Lord CorporationInventors: Edward F. Tokas, Ken C. Caster, Mark A. Weih

Patent number: 6268422Abstract: An adhesive composition containing a polyvinyl alcohol-stabilized butadiene polymer latex and a methylene donor compound. The butadiene polymer latex is prepared by an emulsion polymerization in the presence of polyvinyl alcohol. The adhesive composition may also contain other optional ingredients such as a supplemental polymeric film-forming component, a nitroso compound crosslinker, a maleimide compound crosslinker, a vulcanizing agent, and an acid-scavenging compound. The polyvinyl alcohol-stabilized butadiene polymer latex and methylene donor compound combine to provide a tightly crosslinked, robust film which provides for excellent adhesion and environmental resistance.Type: GrantFiled: December 4, 1995Date of Patent: July 31, 2001Assignee: Lord CorporationInventors: Mark A. Weih, Helmut W. Kucera, Patrick A. Warren, Douglas H. Mowrey

Patent number: 5300555Abstract: A butadiene homopolymer latex is prepared by emulsion polymerizing appropriate monomers in the presence of polyvinyl alcohol and a stabilizing solvent. The butadiene homopolymer latices can be prepared without problems of coagulation and can be utilized effectively in adhesive compositions without the use of volatile solvents. Adhesive bonds prepared from the butadiene homopolymer latices also avoid the side effect problems associated with polymers prepared utilizing conventional surfactant-based emulsion polymerization techniques.Type: GrantFiled: May 31, 1991Date of Patent: April 5, 1994Assignee: Lord CorporationInventors: Mark A. Weih, Gregory J. Czarnecki

Patent number: 5200459Abstract: A butadiene heteropolymer latex is prepared by emulsion polymerizing appropriate monomers in the presence of polyvinyl alcohol and a stabilizing solvent. The butadiene heteropolymer can be a butadiene copolymer or terpolymer prepared from butadiene monomers and comonomers such as .alpha.-haloacrylonitrile and acrylic acid. The butadiene heteropolymer latices can be prepared without problems of coagulation and can be utilized effectively in adhesive compositions without the use of volatile solvents. Adhesive bonds prepared from the butadiene heteropolymer latices also avoid the side effect problems associated with polymers prepared utilizing conventional surfactant-based emulsion polymerization techniques.Type: GrantFiled: May 31, 1991Date of Patent: April 6, 1993Assignee: Lord CorporationInventors: Mark A.
