Abstract: 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.

Abstract: 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.

Abstract: 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.
