Polymer Chemistry and Its Scope

How do changing demands in society lead to polymer invention? How are monomers bonded in nature to form our body’s building blocks? How do scientists mimic nature in labs? How does the several-fold change in molecular weight from monomer to polymer result in different sets of properties? Most of the polymeric materials around us are synthesized in different ways, depending upon end usage. This course will help the students to understand the need and importance of polymers in today’s world. Interesting chemical aspects of synthesis of polymeric architectures from small molecules will be explored.
