FAQs on Polymerization Technique: Bulk Video Lecture - CSIR NET Crash Course for Chemical Science - CSIR NET Chemical Science

1. What is bulk polymerization?
Ans. Bulk polymerization is a technique where the monomer is polymerized in the absence of any solvent. The reaction takes place in a single phase, usually in a reactor, without the need for a solvent to dissolve the monomer.
2. What are the advantages of bulk polymerization?
Ans. Bulk polymerization offers several advantages such as higher reaction rates, reduced processing costs, and simplified purification processes since there is no need to remove solvent. It also allows for the production of high molecular weight polymers.
3. What are the limitations of bulk polymerization?
Ans. One limitation of bulk polymerization is the potential for heat buildup due to the exothermic nature of the reaction, which can lead to thermal runaway. It can also be challenging to control the reaction parameters such as temperature and mixing in bulk polymerization.
4. How is bulk polymerization different from solution polymerization?
Ans. In bulk polymerization, the reaction takes place in the absence of a solvent, while in solution polymerization, the monomer is dissolved in a solvent. This difference affects the reaction kinetics, heat transfer, and overall process conditions.
5. What are some common polymers produced through bulk polymerization?
Ans. Some common polymers produced through bulk polymerization include polyethylene, polypropylene, and polystyrene. These polymers are widely used in various industries due to their mechanical properties and versatility.
