Chemistry Question on Polymers
Which one of the following is not a condensation polymer ?
A
Glyptal
B
Dacron
C
Neoprene
D
Melamine
Answer
Neoprene
Explanation
Solution
Neoprene is not a condensation polymer. It is an addition polymer.
Neoprene is made from monomer chloroprene (2-chlorobuta-1,3-diene).
Dacron, Melamine and Glyptal are condensation polymers.
Dacron (also known as terylene) is a polyester made by condensation polymerisation of ethylene glycol and dimethyl terephthalate.
Glyptal is a copolymer of ethylene glycol and phthalic acid.
Melamine (or formaldehyde melamine polymer) is obtained from condensation polymerisation of melamine with formaldehyde.
