Polyvinyl Alcohol Shuangxin Sandy Wanwei 1788 2488 2688

The physical properties of polyvinyl alcohol are affected by the chemical structure, degree of alcoholysis, and degree of polymerization. The main structure in the polyvinyl alcohol molecule is 1,3-propanediol, which is the "head and tail" structure. The degree of polymerization of polyvinyl alcohol is divided into ultra-high degree of polymerization (molecular weight 250,000 to 300,000), high degree of polymerization (molecular weight 170,000 to 220,000), medium degree of polymerization (molecular weight 120,000 to 150,000) and low degree of polymerization (molecular weight 25,000 to 35,000). ). There are generally three types of alcoholysis degrees: 78%, 88%, and 98%. The alcoholysis degree of partial alcoholysis is usually 87% to 89%, and the alcoholysis degree of complete alcoholysis is 98% to 100%. The thousand and hundreds digits of the average degree of polymerization are often placed in front, and the percentage of alcoholysis degree is placed in the back. For example, 17-88 means that the degree of polymerization is 1700 and the degree of alcoholysis is 88%. Generally speaking, as the degree of polymerization increases, the viscosity of the aqueous solution increases, and the strength and solvent resistance after film formation increase, but the solubility in water and the elongation after film formation decrease.
