Polyvinyl alcohol is obtained through the alcoholysis of polyvinyl acetate. Its degree of alcoholysis refers to the percentage of the number of vinyl alcohol units in the molecular chain to the total number of molecular structural units. …
High degree of polymerization PVA has excellent strength and durability due to its high degree of polymerization, and is an important raw material for preparing high-strength materials. High degree of polymerization is generally above 5000. …
Low degree of polymerization PVA has good water solubility and plasticity due to its lower degree of polymerization and shorter molecular chain. These properties make low-polymerization PVA widely used in many fields. The degree of …
