1. Briefly explain how ‘emulsion polymerization’ works
2. What is ATRP, and how does it make radical polymerizations more “living”?
Homework Answers
Solution 1
Emulsion polymerisation- It is a radical polymerisation which involves an emulsion incorporating monomer, surfactant and water.
example- Oil in water emulsion is a common example of emulsion polymerisation. In this oil droplets which are monomers are emulsified with surfactant in continuous phase of water.
How it works -
The process involves application of emulsifier to emulsify hydrophobic polymers through aqueous phase by emphiphatic emulsifier. After that production of free radicals with oil soluble or water soluble initiators. It involves reduction of biomolecular termination of free radicals because of segregation of free radicals among monomer swollen polymer particles.
