  • Patent number: 6001922
    Abstract: This invention provides the preparation of water-dispersible polyester/acrylic hybrids via a two-stage emulsion polymerization process. For example, methacrylic acid and/or 2-hydroxyethyl methacrylate are copolymerized with styrene/acrylic monomers to yield a relatively hydrophilic and hydro-plasticized first stage. Subsequent additions of hydrophobic monomers to this first stage "seed" results in an inversion of the latex such that the more hydrophilic first stage is at the particle surface. This results not only in improved stability of the resulting latex without the use of additional surfactants, as evidenced by the production of reduced amounts of coagulum, while it also offers relatively low minimum filming temperatures due to the hydroplasticization of the shell of the particle. Furthermore, the use of the water-dispersible polyester results in extremely fine latex particle sizes which can significantly enhance coating properties such as film gloss and clarity.

  • Patent number: 5990199
    Abstract: The invention relates to indicator ink compositions that contain a water-based dispersion of a phenol-formaldehyde resin, at least one colorant and an amine-terminated catalyst. These indicator ink compositions are fixed to a surface, such as by drying, and respond to specific conditions of time, temperature, humidity, pressure and the presence or absence of certain chemicals by changing color. Compositions provide a means for detecting exposure to a predetermined condition and can be fixed or otherwise attached to nearly any article or designed into patterns on materials. Exposure of the indicator ink to the specific condition, the indicator ink provides a permanent detectable record of the event. Further, by varying the amount of amine-terminated catalyst in the formulation, the specific conditions at which the indicator composition will change color can be altered. Such compositions are specifically useful for determining the effectiveness of a sterilization process.

  • Patent number: 5134176
    Abstract: A gel-forming composition capable of plugging highly permeable zones in a subterranean formation. The composition comprises water, a viscosifying amount of a water-dispersible polyvinyl amine copolymer and a crosslinking agent which is a mixture of an aldehyde and a phenolic component in an amount effective to cause gelation of the aqueous solution of the copolymer. The resultant gel is exceptionally thermally stable and, therefore, can be used as an effective profile control agent in all enhanced oil recovery operations, including steam flooding.
