PVA can be regarded as a linear polymer with secondary hydroxyl groups. The hydroxyl group in the molecule has high activity and can carry out typical chemical reactions of low alcohols, such as esterification, etherification, acetalization, etc. It can also react with many inorganic compound or organic compounds.
Applications of PVA in the textile industry as a spinning size, fabric finishing agent, and vinylon fiber raw material; used as a polymerization emulsifier and dispersant in the chemical industry; used as a binder in the wood and paper industries; used in agriculture as soil amendments, pesticide adhesion enhancers, polyvinyl alcohol films, and PVB raw materials;
