Step-by-step solution

Polythene is an addition polymer formed by the repeated addition of ethene monomers. Polyacrylonitrile is an addition polymer formed by the addition polymerization of acrylonitrile. Teflon is an addition polymer formed by the addition polymerization of tetrafluoroethene. Dacron (also known as terylene) is a condensation polymer formed by the condensation polymerization of ethylene glycol and terephthalic acid with the elimination of water molecules. Answer: Dacron
