Patent number: 6645562Abstract: A method of preparing a curable coating and a method of curing the curable coating are disclosed. The curable composition from which the curable coating is prepared may be applied to the surface of a substrate in neat form or in aqueous medium to produce the coating. Curing of the curable coating may be accomplished by chemical generation of free radicals, by electrochemical generation of free radicals, by electron beam, by photochemical generation of free radicals, or by other electromagnetic irradiation.Type: GrantFiled: June 27, 2002Date of Patent: November 11, 2003Inventors: Gary David Greenblatt, Ward Thomas Brown, Michael Damian Bowe, Richard Foster Merritt, Ronald Scott Beckley, Barry Clifford Lange, Robert Wilczynski, David William Whitman, Martha Harbaugh Wolfersberger

Patent number: 6566549Abstract: A continuous process for oligomers which do not contain, as polymerized units, carboxylic acid-containing monomers and their salts, including the steps of: (1) forming a reaction mixture, substantially free of carboxylic acid-containing monomers and their salts, containing: (i) 0.5 to 99.95% by weight of the reaction mixture of at least one ethylenically unsaturated monomer; and (ii) 0.05 to 25% by weight, based on the weight of the ethylenically unsaturated monomer, of at least one free-radical initiator; and (2) continuously passing the reaction mixture through a heated zone wherein the reaction mixture is maintained at a temperature of at least 150° C. and a pressure of at least 30 bars for from 0.1 seconds to 4 minutes to form terminally-unsaturated oligomers. In addition, processes for forming oligomers of vinyl acetate and oligomers of vinyl alcohol are disclosed. Mixtures of fully saturated and terminally unsaturated oligomers are also disclosed.Type: GrantFiled: December 15, 1998Date of Patent: May 20, 2003Assignee: Rohm and Haas CompanyInventors: Gary David Greenblatt, Barry Clifford Lange, Michael Damian Bowe, Richard Foster Merritt, Robert Wilczynski, Gary Robert Larson, Lori Marie Petrovich, David William Whitman

Publication number: 20030065192Abstract: Novel antimicrobial compounds based on 5-substituted 3-isothiazolones, where the 5-substituent is an aryl or heterocyclic ether/thioether group, are disclosed. These 5-substituted 3-isothiazolones provide enhanced antimicrobial activity over that of related 3-isothiazolones, particularly when the 5-substituent is a substituted pyridinyl thioether group.Type: ApplicationFiled: December 12, 2001Publication date: April 3, 2003Inventors: Tirthankar Ghosh, Barry Clifford Lange, Eileen Fleck Warwick

Publication number: 20020137857Abstract: The invention relates to a curable composition and a process of preparing the curable composition. The process comprises (a) forming an oligomer from oligomerization of a mixture of a monomer A having a functional group and a monomer B at a temperature in the range of from 150° C. to 650° C., a pressure in the range of from 3 MPa to 35 MPa and the pressure is high enough to maintain the reaction mixture in a fluid state and a residence time in the range of from 0.1 second to 4 minutes; and (b) reacting a modifier having at least one reactive moiety with the oligomer through a reaction between the reactive moiety of the modifier and the functional group of the monomer A in the oligomer, and the modifier further comprises a curable group.Type: ApplicationFiled: April 13, 1999Publication date: September 26, 2002Inventors: BARRY CLIFFORD LANGE, MICHAEL DAMIAN BOWE, RICHARD FOSTER MERRITT, ROBERT WILCZYNSKI, WARD THOMAS BROWN, RONALD SCOTT BECKLEY

Patent number: 6451951Abstract: The present invention relates to an oligomer with a semi-telechelic nitrogen-functionality and at least one ethylenic unsaturation pendant to the backbone of the oligomer. In addition, a process is provided to prepare the semi-telechelic nitrogen-functional oligomer. The semi-telechelic nitrogen-functional oligomer is useful as a dispersant for pigments in radiation curable formulations.Type: GrantFiled: June 21, 2001Date of Patent: September 17, 2002Assignee: Rohm and Haas CompanyInventors: Ronald Scott Beckley, Barry Clifford Lange, David William Whitman, Jo Ann Arceneaux, Michael Christopher Kramer, Peter Thomas Weissman
