The solubility of modified PVA varies with the degree of alcoholysis and degree of polymerization. PVA with partial alcoholysis and low polymerization degree dissolves extremely fast, while PVA with intact alcoholysis and high polymerization degree dissolves slowly. As a general rule, the effect on the solubility of PVA is that the degree of alcoholysis is greater than the degree of polymerization. PVA dissolution is stopped in stages, namely: affinity-swelling-infinite swelling-dissolution. Film-forming PVA is easy to form a film. The mechanical properties of the film and the tensile strength of the film increase with the degree of polymerization and alcoholysis to enhance the adhesion. PVA has good adhesion to hydrophilic cellulose. Under normal circumstances, the higher the degree of polymerization and alcoholysis, the stronger the bonding strength.

Bog gum is also called Bog gum, which is derived from the exudate of the trunk of the Acacia genus of the leguminous family, so it is also called Acacia gum. The main components of primary gum are macromolecular polysaccharides and their calcium, magnesium and potassium salts. It mainly includes aldose, galactose, and glucuronic acid. The good-quality raw gum is amber in color, and the particles are large and round. It is mainly produced in Africa. At present, there are also powdered primary gums that have been refined, which is more convenient to use. Process features: 1. No solvent is added, propylene monomer is polymerized in liquid phase in a tank reactor in liquid phase, and propylene is copolymerized in a fluidized bed reactor; 2. The process is simple, less equipment, and low investment. The power consumption and production cost are low; 3 the homopolymerization adopts the Hypol process in the tank stirred reactor, or the Spheripol process in the loop reactor, and both the random copolymerization and the block copolymerization are carried out in a stirred fluidized bed.
