Which of the following polymers involves the repeated loss of small molecules at the time of polymerization?

Step-by-step solution

Polymers that involve the repeated loss of small molecules such as water, alcohol, or hydrogen chloride during their formation are called condensation polymers. Teflon is an addition polymer formed by the polymerization of tetrafluoroethylene without the loss of any small molecules. Polyacrylonitrile is an addition polymer formed by the polymerization of acrylonitrile. High density polythene is an addition polymer formed by the polymerization of ethene. Polyester is a condensation polymer formed by the reaction bet
