The water soluble polymer forms a strong and resilient bubble wall. The surfactant(s) lowers the surface tension of the solution to create a bubble blowing film. The fast evaporating solvent or solvent blend acts to harden the bubble wall by dehydration and rapid evaporation. Bubbles blown from the solution will air dry within seconds and exhibit extraordinary strength. The bubbles do not evaporate and resist breakage upon collision with a dry surface. The bubbles remain translucent and fully preserved for hours or even days while resting on a surface.

  • Patent number: 7070731
    Abstract: The present invention provides a new dispersion stabilizer that satisfies, at a high level, the performances required for a dispersion stabilizer used for suspension polymerization. A method of producing a dispersion stabilizer that is useable for suspension polymerization of a vinyl compound and contains a vinyl alcohol polymer (A) includes producing the vinyl alcohol polymer (A) by heat-treating a vinyl alcohol polymer (B) at a temperature of 90 to 180° C. for 0.5 to 20 hours in an atmosphere in which an oxygen concentration is 8000 ppm or lower. The vinyl alcohol polymer (B) has a saponification degree of at least 60 mol % and contains a residual acetic acid group whose block character is in the range of 0.3 to 0.6.

  • Patent number: 7067575
    Abstract: A water-soluble film made from a resin composition comprising (A) 100 parts by weight of an anionic group-modified polyvinyl alcohol having a viscosity of 10 to 35 mPa·s measured at 20° C. with respect to a 4% by weight aqueous solution thereof, an average degree of hydrolysis of 80.0 to 99.9% by mole and a rate of anionic group modification of 1 to 10% by mole, (B) 20 to 50 parts by weight of a plasticizer, (C) 2 to 30 parts by weight of a filler, and (D) 0.01 to 2.5 parts by weight of a surfactant. The water-soluble film has an excellent water solubility, and is not gelled or insolubilized even if chemicals containing a boric acid substance, particularly sodium perborate, are packaged therein or even if it is put in an aqueous solution of a boric acid substance, particularly sodium perborate.

  • Patent number: 7037350
    Abstract: A composition for chemical-mechanical polishing, comprising an aqueous solution and an abrasive that comprises polymer particles, is described. The polymer particles carry an electrical charge, such that nearby particles repel one another. Accordingly, aggregation of polymer particles may be reduced, minimized or eliminated. The composition may additionally comprise an oxidizing agent. A method of using the composition to polish a substrate surface, such as a substrate surface having a metal surface feature or layer, is also described. A substrate so polished may exhibit good surface characteristics, such as a relatively smooth surface or a reduced number of, or a lack of, microscratches on the surface of the substrate.

  • Patent number: 7019054
    Abstract: A formulation, and a process for making same, is disclosed which is useful as a coating or treatment for imparting oil and grease resistance to an underlying substrate. The formulation does not contain any fluorochemicals. At the same time, however, the formulation provides oil and grease resistance properties that are equivalent to known coatings and treatments which contain fluorochemicals, particularly those coatings which are permitted to come into direct contact with food products. Therefore, the formulation of the present invention is ideal for use as a coating for paper and paperboard, including paper packaging such as that utilized in food wrappers, food containers, food receptacles and the like, and for other shaped articles. The formulation is also useful as a coating or treatment for providing release properties to an underlying substrate without the use of silicone.

  • Patent number: 7014909
    Abstract: Volatile organic compounds containing carbonyl groups can be released by lithographic printing materials including inks, fountain solutions and printed materials. Volatile organic compounds containing carbonyl groups can also have a serious negative impact on the taste or odor of staple materials such as foodstuffs. The volatile materials can be retained in the lithographic compositions and printed materials can be trapped in the printed materials using an improved reactive technology involving a chemically reactive trap for such volatile carbonyl containing compounds.
