Patent number: 6599973Abstract: A polymeric dispersant for pigments based on an acrylic graft copolymer wherein the graft copolymer has a weight average molecular weight of about 5,000-100,000 and comprises a hydrophobic polymeric backbone and discrete anionic and nonionic hydrophilic side chains attached to the backbone. These graft copolymers are useful as dispersants in aqueous systems, and are particularly useful in formulating exterior water borne coatings for automobiles and trucks.Type: GrantFiled: September 27, 2000Date of Patent: July 29, 2003Assignee: E. I. du Pont de Nemours and CompanyInventors: Karyn B. Visscher, Patrick F. Mc Intyre

Publication number: 20030125453Abstract: A polyvinyl alcohol copolymer latex composition comprises an intimate polymer composition obtained from 10% to 60% by weight of a substantially hydrolyzed low molecular weight polyvinyl alcohol (PVOH); 2% to 80% by weight of at least one diene; 2% to 80% by weight of at least one hydrophobic monomer other than a diene and optionally either up to 10% by weight of at least one hydrophilic ethylenically unsaturated acid monomer or up to 40% by weight of a cationic monomer. The copolymer latex composition can be prepared as an emulsion from an aqueous blend of the above listed monomers which are generally added at various stages during the polymerization and a free radical initiator, surfactants, and, if desirable, chain transfer agents. Up to 80% of the PVOH may be added after the monomers have been polymerized.Type: ApplicationFiled: December 19, 2002Publication date: July 3, 2003Inventors: Nick G. Triantafillopoulos, Carla B.

Patent number: 6534562Abstract: The present invention provides a tough denture and a method for producing the denture, which includes solid PMMA as a main component, being added to polar elastomer selected from a group of polyacrylate rubber copolymer, methylmethacrylate-alkylacrylate-styrene terpolymer, and fluororubber, and is fabricated in a process of being mixed and injected into a denture mold. A PMMA denture of present invention shows improved safety to living organisms and increased productivity of molding because of excellent mechanical properties and remarkable elution volume decrease after polymerization in comparison with ordinary type dentures of heat-polymerized PMMA. Furthermore, it is possible to widely apply the denture clinically because of good adaptability in oral applications with economical advantages.Type: GrantFiled: March 20, 2001Date of Patent: March 18, 2003Assignee: BMG Inc.Inventors: Shokyu Gen, Sadami Tsutsumi, Toshio Kita
