ABSTRACT Polyvinyl alcohol APV is one of very few high molecular weight commercial polymers that are water soluble, the basic properties of PVA such as water solubility depend on the degree of replacement of acetate groups by hydroxyl groups (degree of hydrolysis) and the degree of polymerization. Vinyl ester resins have been widely recognized as materials with excellent resistance to a wide variety of commonly encountered chemical environments. Vinyl ester resins are used to fabricate a variety of reinforced structures or mechanical equipments .The resin is issued from bulk,solution,or suspension polymerization of a vinyl monomer,vinyl acetate .It has now been found that the use of an initiator system, the hydroxyl-containing aromatic amines and a diacyl peroxide includes, can significantly reduce the odor and, on the basis of the available data, toxicity of the resulting slurry of the beads. Keywords : Polyvinyl acetate PVAc ,Polyvinyl alcohol APV, peroxy/amine catalyst saponification, coating.
