Interpretation:
The second step reaction of cationic
Concept Introduction:
Polymerization is the process that consists linkage of smaller molecular together into a large unit that called as a
Anionic polymerization: This polymerization is taken place due to the action of nucleophiles on an electron deficient site of the given monomer. This polymerization occurs in three steps, initiation, propagation and termination.
>Cationic polymerization This polymerization is taken place due to the action of electrophiles on an electron rich site of the given monomer. This polymerization occurs in three steps, initiation, propagation and termination.
