摘要： A sulfonic acid modified polyvinyl alcohol resin comprising up to 15 mol % of a first comonomer comprising sulfonic acid groups. The modified polyvinyl alcohol resin has a hydroxyl unit content of at least 65 mol % and a gel fraction of 3.2 or less. Further, the modified polyvinyl alcohol resin has a disintegration time of 85 seconds or less, as measured in a mixture of 50 vol % water and 50 vol % isopropyl alcohol at 23° C. Additionally, the modified polyvinyl alcohol resin has a hard component present in a component ratio of 10% or greater and 55% or less and having a relaxation time of 0.0091 milliseconds or greater and 0.0104 milliseconds or less, as measured by the pulsed NMR Solid Echo method at 80° C. Also disclosed are methods for producing the sulfonic acid modified polyvinyl alcohol resins, which may advantageously be used in inks, paints, paper coatings, emulsions, or films.

摘要： Dispersing agents useful in a suspension polymerization process may be formed based on polyvinyl alcohols and processes discloses herein. The dispersing agent may include, for example: a polyvinyl alcohol having a degree of hydrolysis in the range from 60 to 80 mol %; an absorbance of not less than 0.3 measured at a wavelength of 320 nm with respect to a 0.1 wt % aqueous solution of the polyvinyl alcohol; a block character of remaining ester groups in the range from 0.4 to 0.5; and a cloud point in the range from 35° C. to 50° C. measured with respect to a 1 wt % aqueous solution of the polyvinyl alcohol. Carbonyl groups are theorized to be present along the polymer chain, which may be quantified by 1-H NMR spectra peaks.

摘要： A water soluble film useful in unit-dose chemical packaging is disclosed. The film may include: a water soluble saccharide and a polyvinyl alcohol copolymer consisting essentially of: (a) from 80 to 99 mole percent of vinyl alcohol and vinyl ester monomer; and (b) from 1 to 20 mole percent of a pyrrolidone comonomer. Such compositions may be used to provide a water-soluble film simultaneously satisfying requirements in regard to water solubility, biodegradability, and physical properties, even when used for packaging a broad range of harsh, oxidizing chemicals.

摘要： Various processes and methods are disclosed for incorporating polyvinyl alcohol additives into products. In one embodiment, polyvinyl alcohol particles are dissolved in a solvent without the use of external heat to form a polyvinyl alcohol solution for incorporation into a product. In an alternative embodiment, polyvinyl alcohol particles are directly incorporated into a starch-based adhesive composition. Through the processes of the present disclosure, solid polyvinyl alcohol particles can be delivered directly to a manufacturing facility where the product that incorporates the polyvinyl alcohol additive is being made or formulated. In this manner, since the polyvinyl alcohol particles are not predissolved, the costs associated with shipping and transporting the polyvinyl alcohol product are greatly reduced.

摘要： A separator film for an electric battery is provided to substantially eliminate electric contact between an anode component and a cathode component. The film includes a vinyl alcohol copolymer with functional comonomer units such as sulfonic acid functionalized units or salts thereof. The films are desirable for use in battery separators because they exhibit superior resistance to degeneration by oxidation, enabling the manufacture of batteries with improved conductivity, longer discharge times, and longer cycle lives.
