Patent number: 6706414Abstract: The uncrosslinked liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate-functional donor compounds with multifunctional acrylate acceptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from ≧1:1 to ≧13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate in the presence of a catalyst comprising an epoxy moiety and a quaternary salt. Unusable gelled or cured oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.Type: GrantFiled: September 26, 2002Date of Patent: March 16, 2004Assignee: Ashland Inc.Inventors: Laurence G. Dammann, Michael L. Gould

Patent number: 6673405Abstract: About 0.001 to 5 parts by weight of a hindered phenol-series compound, about 0.01 to 5 parts by weight of a weather (light)-resistant stabilizer, and about 0.001 to 10 parts by weight of a spiro-compound having a triazine ring are added to 100 parts by weight of a polyacetal resin. The spiro-compound may be a compound represented by the following formula (1). The polyacetal resin composition may further comprise a coloring agent, a processing stabilizer, a heat stabilizer, and others. wherein R1 and R2 are the same or different, each representing an alkylene group, an arylene group, or an aralkylene group.Type: GrantFiled: May 13, 2002Date of Patent: January 6, 2004Assignee: Polyplastics Co., Ltd.Inventor: Hatsuhiko Harashina

Patent number: 6652970Abstract: The present invention is directed toward compositions that are chemically different after application to a substrate as compared to the composition prior to its application. A method of the invention comprises a method of transitioning a crosslinked polymer composition from a first chemical state to a second chemical state. Advantageously, compositions of the invention are relatively stable after transformation to their altered, or second, chemical state.Type: GrantFiled: July 7, 2000Date of Patent: November 25, 2003Assignee: 3M Innovative Properties CompanyInventors: Albert I. Everaerts, Charles M. Leir, Roger A. Mader, Peter A. Stark
