Polyacrylonitrile - Wikipedia
网页Polyacrylonitrile (PAN) is a synthetic, semicrystalline organic polymer resin, with the linear formula (CH 2 CHCN) n. [2] Almost all PAN resins are copolymers with acrylonitrile as the main monomer. PAN is used to produce large variety of products including ultra filtration membranes, hollow fibers for reverse osmosis, fibers for textiles, and ...

Polyacrylonitrile fibers - ScienceDirect
网页2018年1月1日 · Polyacrylonitrile degrades before reaching its melting point (320°C). Water, on the other hand, has a plasticizing effect on acrylic polymer and blocks the polar interactions between nitrile groups, and causes a lowering of melting point (∼180°C at 33%W water), thus making melt spinning possible ( Frushour, 1981 ).
