  • Melt-processed blends containing poly(vinyl alcohol)
    Patent number: 5753752
    Abstract: Polymers containing a high percentage of vinyl alcohol units are difficult to process into sheet, film, injection-molded objects, or fibers. Such melt-processing is greatly enhanced by admixing certain core/shell copolymers having a rubbery, preferably crosslinked core mainly of units derived from butadiene, and an outer shell mainly of a copolymer of styrene and acrylonitrile. Such copolymers do not require the presence of functional groups capable of reaction with the hydroxyl groups of the poly(vinyl alcohol).
    Type: Grant
    Filed: February 7, 1997
    Date of Patent: May 19, 1998
    Assignee: Rohm and Haas Company
    Inventors: Thierry Christian Claude Diaz, Jean-Philippe Gaetan Meyer, Carlos Alfonso Cruz
  • Melt-processed blends containing poly(vinyl alcohol)
    Patent number: 5744546
    Abstract: Polymers containing a high percentage of vinyl alcohol units are difficult to process into sheet, film, injection-molded objects, or fibers. Such melt-processing is greatly enhanced by admixing certain hydrogenated block copolymers formed by sequential anionic polymerization of butadiene and styrene, followed by hydrogenation, then followed by grafting of maleic anhydride.
