Patent number: 7122605Abstract: The invention relates to a method of making an acrylic graft polymer, especially a urethanized acrylic graft polymer. The method of the invention requires an ethylenically unsaturated monomer mixture (a) comprising a monomer (ai) of a particular structure having at least one cyclic carbonate group and the polymerization of the monomer mixture (a) under free radical polymerization conditions to make an acrylic backbone polymer (b) comprising one or more cyclic carbonate functional groups (bi). At least one grafting moiety (c) is then provided, said grafting moiety (c) comprising at least one amine group (ci) selected from primary amines, secondary amines, and mixtures of both primary and secondary amines. The grafting moiety (c) is then grafted onto acrylic backbone polymer (b) via reaction between the at least one amine group (ci) and cyclic carbonate functional groups (bi) so as to make an urethanized acrylic graft polymer.Type: GrantFiled: November 29, 2001Date of Patent: October 17, 2006Assignee: BASF CorporationInventors: Walter H. Ohrbom, Patricia A. Herrel, John W. Rehfuss

Patent number: 7087675Abstract: The ?-hydroxy carbamate, ethylenically unsaturated monomer of the invention can be polymerized as a homopolymer or copolymerized with other monomers. The polymerization can be carried out in an aqueous medium. The ?-hydroxy carbamate monomer is polymerized to form water-soluble homopolymers or, if polymerized as a mixture with one or more comonomers, copolymers that are soluble, emulsifiable, or dispersible in water. The ?-hydroxy carbamate monomer can be used as a replacement monomer for acrylamide.Type: GrantFiled: March 19, 2003Date of Patent: August 8, 2006Assignee: BASF CorporationInventors: Walter H. Ohrbom, Patricia A. Herrel

Patent number: 6838530Abstract: The invention provides a method of making a number of different multifunctional acrylic materials from a limited number of starting materials. The method of the invention requires the product of a masterbatch of an acrylic oligomer or polymer having two or more cyclic carbonate functional groups. A first portion of the masterbatch is then reacted with ammonia and a grafting material (c) in either successive or simultaneous reactions to provide a first multifunctional acrylic oligomer or polymer. Additional portions of the masterbatch may be reacted with ammonia and other grafting materials (c), different from the first grafting material (c), in either successive or simultaneous reactions to provide different multifunctional acrylic oligomers or polymers.Type: GrantFiled: December 20, 2002Date of Patent: January 4, 2005Assignee: BASF CorporationInventors: Walter H. Ohrbom, Patricia A. Herrel
