FAQs on Polymerization Techniques: Solution & Suspension Video Lecture - CSIR NET Crash Course for Chemical Science - CSIR NET Chemical Science

1. What are the different polymerization techniques used in solution and suspension polymerization?
Ans. In solution polymerization, the polymerization reaction takes place in a solvent, while in suspension polymerization, the reaction occurs in a suspension of monomer droplets in a non-solvent.
2. What are the advantages of solution polymerization over suspension polymerization?
Ans. Solution polymerization typically results in higher molecular weights and better control over the polymerization process compared to suspension polymerization.
3. How does the choice of solvent impact the polymerization process in solution polymerization?
Ans. The choice of solvent can affect the solubility of the monomer and polymer, the reaction rate, the molecular weight distribution, and the overall efficiency of the polymerization process.
4. What is the role of a stabilizer in suspension polymerization?
Ans. Stabilizers are added to suspension polymerization systems to prevent the agglomeration or coalescence of monomer droplets, ensuring uniform polymerization and the formation of spherical polymer particles.
5. How can the polymerization temperature be controlled in solution and suspension polymerization techniques?
Ans. The polymerization temperature can be controlled by adjusting the heat transfer properties of the reactor, the rate of monomer addition, and the use of cooling systems or temperature-control devices.
