⚫Polymers are long chained structures formed by the polymerisation of monomer subunits.

⚫Polymers are of two types, homopolymers and heteropolymers.

⚫Homopolymers contain a single type of monomer subunits while heteropolymers are composed of more than one type of monomer subunits.

⚫For example, cellulose is a homopolymer made of glucose subunits while starch is heteropolymer made of amylase and amylopectin.

Answer 2

What do DNA, a plastic bottle, and wood all have in common? Give up? They are all polymers!

A polymer is a large molecule made up of chains or rings of linked repeating subunits, which are called monomers. Polymers usually have high melting and boiling points. Because the molecules consist of many monomers, polymers tend to have high molecular masses.

The word polymer comes from the Greek prefix poly-, which means "many", and the suffix -mer, which means "parts". The word was coined by Jons Jacob Berzelius in 1833, although with a slightly different meaning from the modern definition. The modern understanding of polymers as macromolecules was proposed by Hermann Staudinger in 1920.
