Question

Dynel is _______Polymer.
A.An additional polymer
B.Co-polymer
C.Homomer
D.All of them

Answer 1

Hint: Dynel is a trade name for a type of synthetic fibre that is used in fibre reinforced plastic composite materials, especially for marine applications. As it is easily dyed, it can also be used to fabricate wigs. Dynel is a copolymer of acrylonitrile and vinyl chloride.

Complete answer:
Dynel is made from a copolymer of acrylonitrile and vinyl chloride. It has the formula \[C{H_2} = CHCl\] . It shares many of its properties with poly acrylonitrile . Polyacrylonitrile has superb tensile strength along with high abrasion resistance. Dynel also resembles PVC to a large extent as it is flame resistant. It is an acrylic resin and it was originally produced by the Union Carbide corporation.
So, Dynel is a co-polymer.

Therefore, the correct answer is option (B).

Note: A copolymer is a polymer that is derived from more than one species of monomer and the polymerization of monomers into copolymers is known as copolymerization. Copolymers that are obtained by the copolymerization of two monomer species are sometimes known to be biopolymers.
If two types of monomeric units take part to form a polymeric structure, it is called a copolymer. Its examples are Nylon 6-6, dacron, glyptal. And If only one type of monomeric unit takes part to form a polymeric structure, it is then called as a homopolymer. Its examples are Glycogen, starch, and chitin. So, the main difference between homopolymer and copolymer is that homopolymers are produced by using a single type of monomer, whereas copolymers are formed by using two different types of monomers.
