Patent number: 6630557Abstract: Compounds of general formula (I), the described methods to prepare these macromonomer compounds, and the copolymer products of these compounds with other vinyl monomers. Wherein W is a capping group; l is 0 or 1; n is 2-1000; m is 2-5; R1 is CH2═CH—CH2—, or CH2═CH—O—R8—; R2 is selected from H, CH2═CH—CH2—, and phenyl or alkyl and wherein R3-R7 is H1, C1-C4 alkyl, and quaternary salts thereof. When R7 and X— is absent, the polymer is amphiphilic. When R7 is alkyl and X— is an anion, the polymer is cationic polymer.Type: GrantFiled: March 13, 2002Date of Patent: October 7, 2003Inventors: Shiping Zhu, Youqing Shen, Robert Pelton

Patent number: 6616981Abstract: A cationic, water-soluble polymer is disclosed as a substrate treatment resin (i.e., coating) to improve color-fastness and adhesion of an ink-jet ink printed onto the substrate. More particularly, a 50% solids aqueous solution of a cationic acrylic resin is provided as the printed substrate treatment resin. Also disclosed is a method for preparing the invention resin.Type: GrantFiled: August 26, 1998Date of Patent: September 9, 2003Assignee: MeadWestvaco CorporationInventors: G. Frederick Hutter, Michael D. Matzinger

Patent number: 6585873Abstract: A crosslinked hydrophilic gel in which the crosslinker used in a compound of Formula I or Formula II or combination thereof. These crosslinked hydrophilic gels provide enhanced separation in electrophoresis. The use of the crosslinkers of Formula I and/or II can result in electrophoresis gels having improved properties including: 1) a broader pore size range; 2) control of pore size distribution; 3) greater resistance to hydrolysis in alkaline media; 4) greater clarity of gels prepared with high concentration of the crosslinkers; and 5) improved background silver staining.Type: GrantFiled: March 22, 2000Date of Patent: July 1, 2003Assignee: University of MelbourneInventors: David Henry Solomon, Greg GuangHua Qiao, Georgia Patras
