Topics in Polymers

1

Basic Concepts and Definitions

  • A polymer is a high molecular mass compound formed by linking many small units called monomers.
  • Monomers are simple, reactive molecules that join together to form polymers.
  • Homopolymers are made from one type of monomer; copolymers are made from two or more different monomers.
2

Types of Polymerization

  • Addition polymerization involves unsaturated monomers adding to a growing chain without loss of small molecules.
  • It proceeds via initiation, propagation, and termination steps.
  • Condensation polymerization involves the elimination of small molecules like H₂O or HCl.
3

Classification of Polymers

  • Based on source: Natural (starch, rubber) and Synthetic (PVC, nylon).
  • Based on structure: Linear, Branched, Cross-linked.
  • Based on molecular forces: Elastomers, Fibers, Thermoplastics, Thermosetting polymers.
4

Commercially Important Polymers

  • Polythene: LDPE (branched) and HDPE (linear); used in bags, pipes.
  • PVC: Made from vinyl chloride; used in raincoats, flooring.
  • Teflon: Heat-resistant; used in non-stick coatings.
