Patent number: 6664360Abstract: Alkoxylated acrylate and methacrylate macromonomers are disclosed that are useful in the preparation of water-reducing additives for concrete, ultraviolet light-curable adhesives, and water-dispersed polyurethanes. The macromonomers are suitably prepared by alkoxylating a hydroxyalkylacrylate or hydroxyalkylmethacrylate in the presence of a DMC catalyst using the continuous addition of starter (CAOS) in order to prevent the formation of by-products during the fabrication of the macromonomer.Type: GrantFiled: July 23, 2002Date of Patent: December 16, 2003Assignee: Arco Chemical Technology, L.P.Inventor: Jianzhong Shen

Patent number: 5990232Abstract: Unique, well defined polyethers containing both hydroxyl-functionality and unsaturation-functionality are prepared by oxyalkylating an unsaturated monomer having at least two free carboxylic acid groups in the presence of an effective amount of a double metal cyanide complex catalyst, optionally, when necessary, in the presence of a free radical polymerization inhibitor. The resulting polyethers are eminently suitable for such uses as polymer polyol stabilizers or stabilizer precursors, and both in situ and ex situ impact modifiers for thermoplastics.Type: GrantFiled: August 25, 1997Date of Patent: November 23, 1999Assignee: ARCO Chemical Technology, L.P.Inventors: Jianzhong Shen, Kenneth G.

Patent number: 5786514Abstract: A process for alkoxylating phenols is disclosed. The process comprises reacting a carbonyl-functionalized phenol with an alkylene oxide in the presence of a substantially non-crystalline double metal cyanide (DMC) catalyst. The process offers fast reaction times at low catalyst levels, reduced problems with condensation side reactions, and low-color, low-viscosity, low-polydispersity alkoxylated phenols. The process enables efficient preparation of alkoxylated carbonyl-functonalized phenols that are especially valuable in the surfactant industry.Type: GrantFiled: December 18, 1996Date of Patent: July 28, 1998Assignee: Arco Chemical Technology, L.P.Inventors: Jianzhong Shen, Sujuan Ba, David M. Braunstein, Haven S. Kesling, Jr.
