PVA block copolymer is a polymer with high application value. It is composed of polyvinyl alcohol (PVA) and another organic polymer block. PVA is a colorless, odorless, non-toxic synthetic polymer with good solubility and plasticity. It has …
Polyvinyl alcohol, an organic polymer. The molecular formula of polyvinyl alcohol is (C₂H₄O), the degree of polymerization is usually 500 to 5000, and the molecular weight is usually 25000 to 300000. Polyvinyl alcohol at room temperature is …
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 …
