  • Patent number: 9006331
    Abstract: The present invention relates to a process for imbibing a step-growth polymer into thermoplastic latex particles and a composition made by such a process. The composition is useful, for example, as a coating, an adhesive, a sealant, a primer, a caulk, a stain, or a filler for a variety of substrates.
    Type: Grant
    Filed: May 2, 2012
    Date of Patent: April 14, 2015
    Assignee: Rohm and Haas Company
    Inventors: Gary William Dombrowski, Zhenwen Fu, Caroline Slone, Andrew Swartz
  • Patent number: 8658742
    Abstract: The present invention relates to a stable aqueous dispersion of thermoplastic polymer particles imbibed with a thermosettable compound. The polymer particles are characterized by having a sufficient concentration of anti-agglomerating functional groups to stabilize the latex against agglomeration. The dispersion is useful as one part of a two-pack formulation.

  • Patent number: 7795343
    Abstract: A polymer composition including polymer particles comprising a first polymer and a second polymer is disclosed. The first polymer optionally has a crosslinked core and has a glass transition temperature in the range of ?30° C. to 100° C. The second polymer comprising select crosslinking groups has a glass transition temperature in the range of ?10° C. to less than 18° C. A coating composition comprising the polymer composition is provided. The polymer composition has good low temperature film formation and provides a film with an acceptable level of hardness.

  • Patent number: 7776975
    Abstract: The present invention relates to a process for preparing an aqueous polymer dispersion containing polymer particles dispersed in an aqueous medium. The process includes providing first polymer particles; adding a hydrophobic polymerization blocker or a styrenic monomer polymerization blocker to the aqueous medium containing the first polymer particles; and preparing second polymer particles in the presence of the first polymer particles. The aqueous polymer dispersion contain first polymer particles and the second polymer that differ according to at least one attribute such as particle diameter, molecular weight, composition, glass transition temperature, or morphology; or contain polymer particles having a broad polydispersity. The aqueous polymer dispersion prepared by the process of this invention is useful in a wide range of applications, including paints, adhesive, binders for nonwovens, and binders for paper coatings.

  • Patent number: 7695770
    Abstract: A multi-stage aqueous emulsion polymer including a first polymer having a calculated Hansch parameter >2.0, the first polymer including 0.5-5 wt. % copolymerized acid monomer, based on the weight of the first polymer, and a second polymer including from zero to less that half the wt. % of acid monomer in the first polymer, based on the weight of the second polymer, the second polymer being from 50% to 85% of the total weight of the first polymer and the second polymer, wherein the difference between the calculated Tgs of the first and the second polymer is from 0° C. to less than 20° C. is provided. Also provided is an aqueous coating composition including the multi-stage emulsion polymer and a method for providing a coating.
