Unit 3- Class 1- High Polymers (Introduction)

Friends in this class we will be starting a new unit called high polymers. Initially lets have an introduction to it.

Definition of polymers: A polymer is a large molecule of high molecular weight obtained by the chemical interaction of many small molecules of low molecular weight of one or more type. The process of manufacture of a polymer is called the polymerization.

Monomers: Small molecules of low molecular weight, which combine to give a polymer, are called monomers.

Degree of polymerization: The number of monomers used in the process is called degree of polymerization.

Functionality: The total number of functional groups or bonding sites present in a monomer molecule is called the functionality of the monomer.

in the next post we will learn more on this, we will be learning the the classification of polymers based on various factors
