Question

PVC is the polymer of

Answer 1

Hint: The repeated units of monomers i.e. compounds formed by the combination of many simple molecules are called polymers. Based upon molecular forces polymers are classified: elastomers, fibers, thermoplastic and thermosetting polymers.
Thermoplastic Polymers gets easily soft when heated
The force between the molecules is between elastomers and fibers and is usually formed by addition polymerization. Examples: PVC, Teflon

Complete answer:
PVC is a thermoplastic polymer; the monomer of PVC is Vinyl chloride. The formation of PVC polymer occurs by an addition reaction in the addition reaction the monomers combine directly with each other without the formation of by-products such as water. Vinyl chloride is an unsaturated molecule and unsaturated molecules generally chain-growth polymers. PVC softens and can be molded easily because there is no cross-linkage between the polymer chains. The structure of PVC is linear and it is a homopolymer which means PVC has only one kind of monomeric unit which is Vinyl chloride.

PVC is synthesized by addition reactions of a large number of vinyl chloride molecules-

Note:
We often get confused between Polymers and macromolecules. All macromolecules and not polymers but all polymers are macromolecules one of the best examples of this is chlorophyll which is not a polymer but is a macromolecule.
PVC has good insulating properties. They are mainly used in the formation of pipes. Due to their attractive properties of low maintenance cost and less weight. They are also used in the manufacturing of leather coats and raincoats.
