METHODS OF POLYMERIZATION

Dear students...

In this post I have shared video link about various methods of polymerization. Hope this will be useful to you. You can also view the study materials form the link given at the end.

Polymerization reaction may take place in any of the three states of matter- solid, liquid, gas. The solid state reactions are usually slow, they are not considered practical for this reason. The gas-phase reactions do take place but normally they require maintenance of high temperatures, a condition in which almost all high molecular weight polymers become unstable. Hence almost all commercial process of polymerization are liquid phase reactions.

LIQUID-PHASE REACTIONS:

→ Homogenous type

 Bulk Polymerization

 Solution Polymerization

→Heterogeneous type

 Emulsion Polymerization

 Suspension Polymerization/Pearl/Bead Polymerization

The homogenous or heterogeneous terms refers only to initial conditions of the system and are not to the subsequent conditions
