PVA is a very versatile water-soluble polymer, performance is between plastic and rubber, appearance is white powder. Water is a good solvent for PVA. PVA has good membranous, PVA formed film with excellent adhesive, frictional resistance, stretching intensity, oxygen insulated. Because PVA with two functional groups of hydrophilic group and hydrophobic group, therefore , it has interface activity, so the PVA can be used as protective colloid of polymer emulsion and suspension polymerization reaction.
