CAS NO:25014-41-9 PAN/Polyacrylonitrile

The advantages of polyacrylonitrile fibers are good weather resistance and resistance to sunlight. After being placed outdoors for 18 months, they can still maintain 77% of their original strength. It is also resistant to chemical reagents, especially inorganic acids, bleach powder, hydrogen peroxide, and general organic reagents. Polyacrylonitrile is unstable to alkali and is prone to coloration when exposed to alkali. It can hydrolyze into sodium polyacrylate in concentrated alkali at temperatures above 80℃. In terms of elasticity and curling properties, it has a significant gap compared to wool.

The polymerization temperature is like a "metronome" for molecular movement. It directly affects the rate of the polymerization reaction, the decomposition speed of the initiator, the balance of chain growth and chain termination, and ultimately determines the molecular weight and viscosity of the polymer. In the free radical polymerization of PAN, the influence of temperature is particularly significant.
