Tetrafluoroethylene, the chemical compound that gives Teflon its name, is C2 F4. Because of its hydrophobic properties and moderately good heat resistance, it is used to coat non-stick frying pans and other cookware. Polythene is a polymer made from the monomer - ethene, which is nH2 C=CH2.
A polymer is a large molecule that is essentially a combination of many subunits. The polymer in Greek refers to many parts. It can be found all around the environment. From the DNA strand, which is a naturally occurring biopolymer, to polypropylene which is used in the world as plastic. Polymers may be naturally found in animals and plants (natural polymers) or may be man-made (synthetic polymers). Different polymers contain numerous physical and chemical properties because of which they find usage in everyday life.
Which of the following is a polyamide polymer? (a) Nylon 6,6 (b) Terylene (c) Teflon (d) Polythene
A polymer of polyamide is nylon 6,6. It contains repeating -CO-NH-, and amide linkages.
