Unformatted text preview: (b) What are the rates of initiation, propagation, and termination (R i , R p and R t )? (c) How long will it take to prepare 1.04 Kg of polystyrene? (d) What is the average polymer molecular weight? (e) If the polymerization temperature is changed to 85 °C, what is the time saving in producing 1.04 Kg polymer and average molecular weight of polymer? 3. Describe an anionic polymerization reaction in details (initiator, monomer, termination agent, their quantities, and reaction conditions) to prepare 104 g polystyrene with molecular weight of 104,000 g/mole. 4. Describe the components of an emulsion polymerization system. Compare the pros and cons of emulsion polymerization as a process condition in comparison to bulk and solution polymerization....
