Question

Orion and acrilan fibers of well-known textile materials of the same name. They are the co-polymers of:
(a) styrene and butadiene
(b) alcohol and ester
(c) acrylonitrile and 2-vinylpyridine
(d) methane and acetone

Answer 1

Co-polymers are those polymers which are formed by the combination of different types of monomers and if you have thoroughly gone through all the polymers and their monomers and properties, then you can easily answer the given statement accordingly. Now solve it.

Complete step by step answer:
- First of all, we should know what polymers actually are. Polymers are the high molecular mass compounds, obtained by joining together a larger number of simple molecules through covalent bonds in a regular manner. And the simple molecules which combine to form a polymer are called the monomers and this process of formation of the polymers is known as the polymerization.
- Now coming next to the copolymers. Copolymers are those polymers which are formed by the combination of two or more different monomers.
- Now considering the statement as;
Orion and acrilan are the trade names of the co-polymer polyacrylonitrile or PAN. It is a polymerized product of the vinyl cyanide i.e. acrylonitrile and is obtained by the addition polymerization of the acrylonitrile in the presence of the catalyst as;
$\begin{aligned} & nC{{H}_{2}}=CHCN\xrightarrow{catalyst}-{{[-C{{H}_{2}}-CHCN-]}_{n}}- \\\ \end{aligned}$
Thus, the copolymers of Orion and acrilan fibers are acrylonitrile and 2-vinylpyridine.
The correct option is option “C” .

Note: Acrilon and orlon are hard, horny and high melting substances and are used as a substitute of wool for making blankets, sweaters, bathing suits etc. and is also used for making synthetic carpets.
