In addition, when the copolymers of the invention are used, a drastic decrease in the water/binder ratio still leads to highly fluid building materials without segregation of individual constituents from the building material mixture occurring.Type: GrantFiled: September 27, 2001Date of Patent: August 17, 2004Assignee: Degussa Construction Chemicals GmbHInventors: Gerhard Albrecht, Christian Hübsch, Hubert Leitner, Harald Grassl, Alfred Kern

Patent number: 6756461Abstract: Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of dicarboxylic monomers such as maleic anhydride, itaconic anhydride or citraconic anhydride. Free radical polymerization is used in the synthesis of the polymers. The polymers may be complexed with ions and/or mixed with fertilizers or seeds to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.Type: GrantFiled: May 15, 2003Date of Patent: June 29, 2004Assignee: Specialty Fertilizer Products, LLCInventors: John Larry Sanders, Grigory Mazo, Jacob Mazo

Patent number: 6723813Abstract: The present invention is a method of preparing an acrylic copolymer having an acid anhydride group with a number average molecular weight of 1,500-5,000 comprising; polymerizing a monomer mixture of a radical polymerizable monomer having an acid anhydride group and another radical polymerizable monomer at a temperature of 150° C. or higher by using a radical initiator, wherein the concentration of the monomer mixture is 50-75 wt %. This method can provide an acrylic copolymer having an acid anhydride group with a relatively low molecular weight that does not cause the problem of yellowing after baking when used in an acid/epoxy curing type clear paint, by means of high temperature polymerization without the use of a large amount of an expensive initiator.Type: GrantFiled: June 17, 2003Date of Patent: April 20, 2004Assignee: Nippon Paint Company, Ltd.Inventors: Tomohito Asai, Shinya Yamada, Yusuke Ninomiya
