Question

Which one is classified as a condensation polymer:
A.Teflon
B.Acrylonitrile
C.Dacron
D.Neoprene

Answer 1

Hint:For this we must have some knowledge about the types of polymers and polymeric substances. This polymer is made up from ethylene glycol and methyl terephthalate.

Complete step by step answer:
Polymers are the substances that are made up by repeating smaller molecules to form long chains. They are of various types depending on the type and the structure. Basically condensation polymers are the polymer which forms through condensation. Smaller molecules such as water leave as a side product during the preparation of such polymers. These polymers are more biodegradable than Addition polymers. Let us see which polymer belongs to which type:
Teflon is an Addition polymer formed by joining the monomer tetrafluoroethene that is abbreviated as TEF.
Acrylonitrile is itself a monomer that is used in preparation of polyacrylonitrile along with many other co-polymers.
Dacron is a condensation polymer made out of ethylene glycol and methyl terephthalate. It is known as polyethylene terephthalate and is abbreviated as PET and PETE. It is a thermoplastic polymer resin.

Neoprene is also an Addition polymer which is formed by free radical polymerization of chloroprene. It is a synthetic polymer.

Hence option C is correct.

Note:
It is used in cloth fiber, food containers, engineering fibers. It is used in fruit packaging. In daily life we find this in carbonated drinks bottles. We can increase the durability of Dacron by mixing it with glass and fibers. It is colourless and semi crystalline in its natural state.
