Polyacrylonitrile Chemical Properties,Usage,Production

Description

Polyacrylonitrile is a kind of synthetic resin manufactured through the free radical polymerization of acrylonitrile. It belongs to the acrylic resin family. It is thermoplastic, and is resistant to most solvents and chemicals because of the strong chemical bonds formed between the nitrile groups. It is a kind of versatile polymer which can be used to produce many kinds of products such as fibers for textiles, ultra filtration membrane, carbon fiber and hollow fibers for reverse osmosis. Its homopolymer can also be used as fibers in outdoor awning, sails for yachts, and fiber-reinforced concrete. It can also be used for production of inherently flame resistant (FR) fabrics.

Chemical Properties

Polyacrylonitrile(PAN) is a derivative of acrylic acid where the carboxylic acid group is replaced by the related nitrile group and presents the molecular formula (C3H3N)n.
PAN is a semi-crystalline polymer and though it is a thermoplastic, it does not melt under normal conditions. Its degradation occurs before it melts and its melting is usually observed at above 300°C. When this polymer is heated up to 200°C, it can be transform into a rigid structure with a release of energy, an occurrence referred to as cyclization.Above the cyclization temperature, this polymer undergoes oxidation, a scenario that confers non-flammability on it. If PAN is heated to above 1000°C under inert atmosphere, it gives a product with a percentage of carbon greater than 90%.This property makes it usable in carbon fiber production.
Some major characteristic properties that render PAN special compared to other polymers include the fact that it is the most resistant polymer to degradation by ultraviolet rays and sunlight and it is highly chemically unreactive and resistant to most organic acids and solvents. In addition, this polymer can be attacked only by concentrated solutions of alkalis and highly polar liquids.PAN in the form of acrylic fiber is resistant to breakages, is soft and comfortable, possesses high thermal insulation properties, and it does not melt maintaining its morphological structure when it is heated.This last property of PAN is utilized for the production of insulation fibers, flame retardant fibers, carbon fiber and blankets for filtration of hot gases.

Uses

Due to its special properties such as stability to UV degradation, low density, high strength and modulus of elasticity, thermal stability, non-fusibility and chemical resistance, Polyacrylonitrile is an important polymer for a wide range of applications.Thus, it is used in textile applications due to its wool-like characteristics, in the making of carbon fiber, filtration membranes, fibers for cement reinforcement, sails for yachts, awning fabrics in outdoor applications, specialist fibers for acoustic and thermal insulation, anti-flame fibers and in the production of felts for hot air filtration systems.
Copolymers containing polyacrylonitrile, which are flame-retardant, are used asfibers to make knitted clothing, like socks and sweaters, as well as outdoor productslike tents. Poly(acrylonitrile-co-butadiene-co--styrene)(ABS) and Poly(styrene-co-acrylonitrile)(SAN) are used as plastics. ABS is a lightweight and very strong polymer. It is so light and strong enough to be used in the production of automobile body parts.Thus, this material render automobiles'lighter using less fuel and thus polluting less.
The strength of ABS emanates from the nitrile groups that are present in its acrylonitrile units. The nitrile groups are very polar; hence, they can be attracted to one another. This occurrence permits opposite charges on the nitrile groups to stabilize one another. This strong attraction holds ABS chains very tightly, thus, itmakes the material very strong.Furthermore, the rubbery polybutadiene present in it makes ABS a tough polymer.
