PREPARATION OF POLY ACRYLONITRILE (HIGH POLYMER)
It is a substance whose molecular structure built up completely from a large number of small units bonded together. Eg: Plastic is the most common example, other than plastic polymers includes hairs, nails etc.
The chemical process which combines several monomers to form a polymeric compound is called polymerization.
PAN is a synthetic, semi-crystalline organic polymer resin and its formula is (C3H3N)n. It doesn’t melt under normal condition. Almost all polyacrylonitrile resins are co-polymers made from the mixline of monomers with acrylonitrile as the main component. It is a component repeat unit in several important co-polymers such as SAN (styrene acrylonitrile).
APPLICATIONS OF PAN:-
1)It is used as fibers in hot gas.
2) Co-polymers containing PAN are used as fibers to make knitted clothing socks
3) It is commonly employed as co-monomer with styrene.
