Patent number: 6376615Abstract: The present invention describes the preparation of copolymers grafted by the so-called “grafting from” method, comprising two steps. In the first step, a polymer of a variable type referred to as poly(M1) is reacted with persistent free radicals of the type diphenyltrialkylsilyloxymethyl to form a reactive polymer poly(M1)F, containing a variable number F of these groups attached to the chain. F represents the average functionality of the reactive polymers and may be predetermined by controlling the ratio of poly(M1) and the free radical generator or TPES. In the second step, poly(M1)F is dissolved in a monomer M2 and then redissociated by heating to temperatures of 110-130° C. to produce the macroradical poly(M1) and the persistent radicals. The macroradical poly(M1) rapidly initiates polymerization whereas the diphenyltrialkylsilyloxymethyl radical stays temporarily on the sideline of the initiation reaction.Type: GrantFiled: October 16, 1998Date of Patent: April 23, 2002Assignee: Centro de Investigacion en Quimica AplicadaInventors: Ramiro Guerrero-Santos, Hortensia Maldonado Textle, Maria Esther De Leon Saenz

Patent number: 6034184Abstract: The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated, functionalized, optionally modified and post treated. The dispersant substances include a copolymer of two different conjugated dienes. The polymers are selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective functionalization. The polymers may be functionalized by a Mannich base condensation reaction. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in their dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.Type: GrantFiled: June 23, 1998Date of Patent: March 7, 2000Assignee: Mobil Oil CorporationInventors: Thomas S. Coolbaugh, Frederick C. Loveless, John E. Marlin, II, Demetreos N. Matthews

Patent number: 6015864Abstract: Proposed is a thermosetting powder coating composition comprising a mixture of particles reactive towards one another, optionally in combination with a catalyst, with a portion of the reactive particles comprising a polymer reactive towards oxetane groups while another portion comprises an oxetane groups-containing cross-linking agent having an oxetane functionality of more than 1. The quantity of oxetane oxygen in the cross-linking agent preferably is at least 0.4 wt. %. The reactive polymer preferably is a polymer having groups reactive towards oxetane, such as carboxyl, epoxy, oxetane, anhydride, and hydroxyl, with preference being given to a polyester or a hydroxypolyacrylate.Type: GrantFiled: May 21, 1998Date of Patent: January 18, 2000Assignee: Akzo Nobel NVInventors: Martinus Adrianus Anthonius Maria Koenraadt, Arie Noomen, Keimpe Jan Van Den Berg, Josephus Christiaan Van Oorschot, Huig Klinkenberg
