Physical properties of 2-pyrrolidone: colorless crystal below 23℃, clear and transparent liquid above 24.6℃, good chemical stability, non-corrosive. It is soluble with lower ketones, alcohols and chloroform.
N-vinylturrolidone is active in chemical properties and easy to be hydrolyzed and polymerized.
Physical properties of polyvinylpyrrolidone: soluble - very soluble in water and halogenated hydrocarbon solvents, alcohols, amines, nitroalkanes and low molecular fatty acids, but insoluble in acetone, ether, turpentine, aliphatic hydrocarbons and alicyc
As a kind of synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compound, such as colloidal protection, film-forming, adhesion, hygroscopicity, solubilization or coagulation, but its characteristics, so peopl
Like all homopolymer series products, pvpk30 contains hydrophilic and oleophilic groups in its molecular structure, which can interact with many solvents, making it soluble in water, a variety of alcohols, carboxylic acids, amines, halogenated and other o
The aqueous solution of pvpk90 is non thixotropic in most cases and has a short relaxation time. When the concentration is very high, it will have a certain structural viscosity; when the shear force is increased, the viscosity will decrease. Controlling
