Chemistry - Polymer Question with Solution | TestHub

Semisynthetic polymers are mostly derived from naturally occurring polymers by chemical modifications. Examples include cellulose derivatives such as cellulose acetate (rayon), cellulose nitrate, and cuprammonium rayon.

Teflon (polytetrafluoroethylene) is a completely synthetic polymer prepared by the polymerization of tetrafluoroethylene under high pressure in the presence of a free radical catalyst.

Therefore, Teflon is not a semisynthetic polymer.

Answer: Teflon
