The two-digit number indicates the degree of polymerization by one-hundredth;the higher the number,the

higher degree of polymerization,so is the viscosity.

The most important properties which the majority of applications depend are degree of polymerization and

degree of hydrolysis.The degree of polymerization is an expression of the size of polymer.The higher the

degree of polymerization of polymer is,the bigger the size and the longer the length of polymer is.Similarly,the

degree of hydrolysis is an expression of the ratio of hydrophilic alcohol group and hydrophobic acetate group.

The properties of PVA are summarized as follows.
