Interpretation Introduction

Interpretation:

Para-methoxystyrene undergoes cationic polymerization more rapidly than styrene need to be explained.

Concept introduction:

Polymerization is a reaction when monomer molecules are reacted to form a polymer chain.  Polymerization can occur via three ways,

  • Cationic polymerization
  • Radical polymerization
  • Anionic polymerization

Cationic polymerization is the polymerization of the monomer (vinyl) with strong electron donating groups.  In this method cationic initiator transfers charge to the monomer which becomes active and further propagates with another molecules.

Anionic polymerization is the polymerization of the monomer (vinyl) with strong electron-withdrawing groups (electronegative groups).  In this polymerization carbanion is the active species.

Radical polymerization is a type of polymerization where the reaction occurs by successive addition of free-radicals.

To explain: To explain why para-methoxystyrene undergoes cationic polymerization rapidly than styrene
