Which from following is a homopolymer ?

Options

  1. APolyacrylonitrile
  2. BBuna - N
  3. CUrea formaldehyde resin
  4. DPolycarbonate

Correct answer

A. Polyacrylonitrile

Step-by-step solution

A homopolymer is a polymer which is formed from only one type of monomer. Polyacrylonitrile is formed by the addition polymerization of a single monomer, acrylonitrile. Buna-N is a copolymer formed from two different monomers, 1,3-butadiene and acrylonitrile. Urea formaldehyde resin is a condensation copolymer formed from urea and formaldehyde. Polycarbonate is a condensation copolymer typically formed from bisphenol A and phosgene. Therefore, polyacrylonitrile is the only homopolymer among the given options.
