Question

Which one of the following is classified as a condensation polymer?
A.Dacron
B.Neoprene
C.Teflon
D.Acrylonitrile

Answer 1

Before answering this question, we should know what polymers are. A Polymer is a macromolecule that is made up of small similar subunits. A combination of monomers form polymers, this process is called polymerization. Polymers are important products of the modern chemical industry.

Complete answer:
Polymers are extremely usable from households to factories. They are natural as well as man-made. They have physical properties like toughness and viscoelasticity. In the field of Biophysics, Macromolecular Science, and Polymer Science we study polymers. Polymers are present in a huge amount on the earth's surface.
Classification based on Mode of Polymerisation – 1. Addition polymers-The addition polymers are framed by the replicate expansion of monomer atoms having a double bond or triple bonds, e.g., the development of polythene from ethene and polypropene from propene. Be that as it may, the expansion polymers shaped by the polymerization of a single monomeric type are known as homopolymers, e.g., polythene. Case - Butadiene-Styrene copolymer(Buna-S)
2. Condensation Polymers- The condensation polymers are set up through response between two, not at all like bi-functional or tri-functional monomeric units. In these responses, little particles like water, liquor, hydrogen chloride, and so forth are expelled. Cases are terylene (dacron), nylon 6, 6, nylon 6, and so on. For instance, nylon 6, 6 are shaped by the buildup of hexamethylene diamine with adipic corrosive.
Dacron or terylene is the best-known instance of polyesters. In the presence of zinc acetate antimony trioxide and by heating a mixture of ethylene glycol and terephthalic acid at 420 to 460 K, it gets created. Dacron fiber (terylene) is used as glass strengthening materials in safety helmets etc. It is wrinkled safe and is used as a piece of blending with cotton and wool fibers.
