Patent number: 7001957Abstract: An improved method of making an ethylene acrylate (AEM) elastomer or a polyacrylate (ACM) elastomer wherein an aqueous solution of hexamethylene diamine (HMDA) is employed as the curative agent rather than hexamethylene diamine carbamate (HMDAC). The HMDA reacts with the curative-site monomer derived from the monoalkyl ester of a 1,4-butene-dioic acid in the presence of water, producing (i.e., after press-curing and any secondary heat-curing) a crosslinked elastomer with properties essentially indistinguishable from that produced using HMDAC as the curative agent.

Publication number: 20040143046Abstract: This invention is directed to formation of a creped nonwoven web. The creped web is formed in a creping process using a polymer emulsion binder formed in an alkylphenol ethoxylate-free surfactant system. The surfactant system comprises a combination of a specific active anionic surfactant (sodium laureth sulfate containing 1 to 12 moles of ethylene oxide) and a specific active nonionic surfactant (a secondary alcohol ethoxylate containing 7 to 30 moles of ethylene oxide or an ethoxylated branched primary alcohol containing 3 to 30 moles of ethylene oxide.Type: ApplicationFiled: January 6, 2004Publication date: July 22, 2004Inventors: Joel Erwin Goldstein, Ronald Joseph Pangrazi

Patent number: 6740691Abstract: A process for treating an aqueous polymer latex/dispersion of synthetic polymers prepared by polymerizing one or more monomeric materials for at least 80%, involving: A. adding to the polymer latex/dispersion a sufficient amount of at least one reducing agent in one or more portions followed by adding at least one free radical generator in such a way that at least the bulk of the reducing agent has been added before addition of free radical generator is started and maintaining the mixture at a suitable temperature for a period of time which is sufficient to reduce the VOC-level of the latex/dispersion to decrease to below 1,500 ppm, preferably to below 1,000 ppm after which B. water vapor and/or gas is/are sparged into the latex/dispersion while the temperature of the latex/dispersion is maintained at a suitable temperature for a period of time which is sufficient to decrease the VOC-level to below 200 ppm, preferably to below 50 ppm, most preferably to below 15 ppm.Type: GrantFiled: September 10, 2002Date of Patent: May 25, 2004Assignee: National Starch and Chemical Investment Holding CorporationInventors: Johanna Maria Sophia Lorteije, Markus Aurelius Von Arx, Rolf Studer, Petrus Leonardus Swinkels

Patent number: 6696518Abstract: The present invention relates to a process for hydrogenating ethylenically unsaturated double bonds in polymers P by reacting an aqueous dispersion of at least one polymer P with hydrogen in the presence of at least one hydrogenation catalyst comprising at least one transition metal selected from rhodium and/or ruthenium and at least one nonionic phosphorus compound capable of forming a coordinative compound with the transition metal, which comprises incorporating the hydrogenation catalyst into the aqueous dispersion of the polymer P without adding a solvent. The present invention also relates to the aqueous dispersions of the hydrogenated polymers P obtainable by this process and to coating compositions comprising such dispersions.Type: GrantFiled: November 27, 2001Date of Patent: February 24, 2004Assignee: BASF AktiengesellschaftInventors: Rolf Dersch, Heiko Maas, Volker Schädler
