Phenyl isocyanate with polyvinyl alcohol

Biologically Active Modification of Polyvinyl Alcohol The Reaction of Phenyl Isocyanate with Polyvinyl Alcohol... [Pg.83]

Here advantage is taken of modification by swelling and adsorption of chemically reactive modifiers and catalysts into the polymer to generate different functional groups. It has been shown that the pendant hydroxyl groups of polyvinyl alcohol (PVA) and poly-2-hydroxy propyl methacrylate can partially be reacted with acetic or benzoic anhydride or phenyl isocyanate to form new structures [44], to form side groups with ester linkages. As a result a copolymer of is produced ... [Pg.268]
