Patent number: 9447215Abstract: This invention provides a multistage emulsion polymer including, as copolymerized units: from 0.5% to 5%, by weight P-acid monomer, based on the weight of the emulsion polymer; from 0% to 0.05% by weight multiethylenically unsaturated monomer, based on the weight of the emulsion polymer; and at least one second monoethylenically unsaturated monomer; the emulsion polymer having a calculated Tg of from ?20° C. to 50° C.; the emulsion polymer is formed by the “pulsed” addition of 75% to 100% of the P-acid monomer during a stage including from 10% to 50% of the total monomer weight, preferably added during the relatively early stages of the polymerization. A multistage polymer/TiO2 composite particle and an aqueous coating composition including the composite particle are also provided.Type: GrantFiled: August 26, 2011Date of Patent: September 20, 2016Assignee: Rohm and Haas CompanyInventors: James Charles Bohling, Steven James Broadwater, Arnold Stan Brownell, John William Hook, III, Reginald T.

Publication number: 20140163160Abstract: The present invention relates to a process for preparing a multistage phosphorus acid functionalized latex polymer comprising the steps of: a) contacting a first acrylic monomer with a first phosphorus acid monomer under emulsion polymerization conditions to form a first stage polymer; then b) contacting the first stage polymer with a second acrylic monomer and a second phosphorus acid monomer under emulsion polymerization conditions to form the latex polymer. The latex polymer is useful as an absorbing polymer for pigment particles used, for example, in coatings formulations.Type: ApplicationFiled: July 25, 2012Publication date: June 12, 2014Applicant: ROHM AND HAAS COMPANYInventors: James Charles Bohling, Arnold Stan Brownell, Catherine Ann Finegan
