PREPARATION OF POLY ACRYLONITRILE (HIGH POLYMER)

POLYMERS:-

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.

POLYMERIZATION:-

The chemical process which combines several monomers to form a polymeric compound is called polymerization.

POLY ACRYLONITRILE:-

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.

Eg:- SAN

    Plastics are very essential in every one’s life time. The general knowledge about the plastic are very important as it is. i have go through this article i believe this article gives me a very good idea about the various types and preparation on PAN

    Preparation is given of the Polyacrylonitrile (PAN) is a synthetic, semicrystalline organic polymer resin, with the linear formula (C3H3N)n. Though it is thermoplastic, it does not melt under normal conditions. It degrades before melting. It melts above 300 y if the heating rates are 50 degrees per minute or above.[1] Almost all polyacrylonitrile resins are copolymers made from mixtures of monomers with acrylonitrile as the main component
