Nylon is classified as a condensation polymer because during its formation

  • A. no by product is formed
  • B. the monomers contain double bonds that open
  • C. a small molecule such as water or hydrogen chloride is eliminated at each linkage
  • D. the polymer is condensed from a gas

Explanation

A diamine and a dicarboxylic acid react so that an amide linkage forms and water is expelled at each join, which is why the polymer contains fewer atoms than the sum of its monomers. Nylon is a polyamide, and terylene, formed from a diol and a diacid, is the analogous polyester. Every condensation monomer needs two functional groups so the chain can grow at both ends.
