  • Patent number: 8192838
    Abstract: The invention relates to polymers whose water solubility may be triggered by changes in pH, salt concentration, concentration of surfactant or a combination of both. The polymer is a copolymer or terpolymer containing from 2 to 60 mole percent of an amine functionality that has been neutralized with a fixed acid. Specifically films formed from these polymers will be insoluble at a higher pH, but will become soluble at a lower pH. The polymers are also insoluble at a higher salt concentration, but become soluble at a lower salt concentration. The polymers can be used to coat or encapsulate active ingredients, that are released based on changes in the environment, such as in the rinse cycle of a dishwasher or laundry washing machine.

  • Patent number: 8148312
    Abstract: The invention provides an aqueous bleaching solution for substrate treatment comprising a source of oxidant and a suspended polymer matrix having a plurality of optically functional particles associated with one or more copolymers present in the polymer matrix. The plurality of optically functional particles are associated with the copolymer during polymerization of at least one hydrophobic and at least one hydrophilic monomer so as to form a polymer matrix useful to impart an aqueous bleaching solution with optically functional properties providing a benefit to the solutions during storage, use and application to substrates for treatment.

  • Patent number: 8106118
    Abstract: A glass adhesion composition containing a copolymer having an acid and a substituted amide, silanol, or amine oxide functionality. The substituted amide, silanol, or amine oxide functionality provide excellent adhesion of the copolymer to glass, silica, sand and other silicon-based substances. The copolymer is useful as a fiberglass binder, and also useful in providing protective coatings on glass sheets. A fiberglass sizing composition is also provided having a copolymer that includes at least one acid group derived from at least one acid monomer, a hydrophobic comonomer, and a crosslinker.

  • Publication number: 20110196054
    Abstract: Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, an infrared attenuating agent, and a polystyrene/polyethylene oxide copolymer are provided. In exemplary embodiments, the blowing agent contains an HFC. The maleic anhydride-styrene copolymer grafted with polyethylene oxide increases the cell size of the polymer foam and offsets or even negates the decreased cell size caused by an HFC blowing agent and/or infrared attenuating agents. In addition, the copolymer of maleic anhydride-styrene grafted with polyethylene oxide has a positive affect on the processability of the blowing agent(s) in the composition by both widening the process window and enhancing the solubility of the blowing agent in the polymer melt. Thus, the polystyrene/polyethylene oxide copolymer present in the inventive composition acts as a cell enlarger, a plasticizer, and a processing aid. A method of forming an extruded foam product is also provided.
