Since the partially alcoholized PVA contains more acetate groups, and the volume of the acetate group is much larger than the hydroxyl group, there is a large steric hindrance, so that the partially alcoholized PVA cannot form a compact crystal structure. It can only form loose structures with large
The degree of alcoholysis has an effect on the water solubility, viscosity, adhesion and serosity of the slurry.1. Water solubility:PVA with fully alcoholysis is poor in water solubility,for example,PVA with Alcoholysis degree more than 99%(Mole fraction) begin to dissolve when it is heated above 9

Melamine formaldehyde molding compound is made of "melamine formaldehyde resin" as a base material, "Alpha" cellulose as a filler, and added with pigments and other additives. It has the characteristics of water resistance, high temperature resistance, non-toxicity, bright color and convenient molding process. It is widely used in various melamine tableware, containers, electrical parts and other molded products. The urea-formaldehyde molding compound and the melamine formaldehyde-formed plastic granule product can be obtained by molding and injection molding; the powdery product is molded to obtain a molded product. Melamine tableware is made of melamine powder by high temperature and high pressure. The melamine resin refers to a melamine formaldehyde resin, and also a melamine formaldehyde molding compound, abbreviated as "MF", which is a resin obtained by polycondensation of melamine powder and formaldehyde under a slight alkali condition. The resin is light in color and therefore free to color.
