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

1,Why add Urea Ad-blue for automobiles?What’s the use of Urea Ad-blue for automobiles?
Urea Ad-blue solution is used for diesel engines. Because diesel engines emit pollutants,such as nitrogen oxides,which are harmful to the atmosphere and the human body.Long-term breathing of such gases can cause respiratory diseases.In order to reduce the harm of such gases to the atmosphere and human beings,the catalytic reaction is carried out with Urea Ad-blue solution for vehicles.The Urea Ad-blue solution produces a reduction reaction with NOX,which produces nitrogen,oxygen and water,thereby reducing the emission of nitrogen oxides,nitrogen and water is harmless to the atmosphere and the human body.
2,Where is the Urea Ad-blue solution used?
No matter what brand of diesel engine,there is usually a special device,something like a box,which contains the Urea Ad-blue solution.When the car is driving,it will continuously discharge nitrogen oxides,and the Urea Ad-blue solution is also consumed,so it needs to be added regularly.
