Polystyrene can be polymerized from the starting monomer
(styrene) pictured below.
a. Anionic polymerization is one method of polymerization that
can be used to generate polystyrene from styrene. Explain what type
of initiator should be used for this reaction
and draw an example of a styrene monomer that has reacted with
initiator.
b. Using this anionic polymerization method and a starting
concentration of 1M styrene and 1mM initiator, what degree of
polymerization (Xn) would you expect if you use up...
Q3 (25 pts) The polymerization is done by the anionic mechanism, and 2 mol of polystyrene is polymerized in tetrahydrofuran (THF). Polymerization was initiated by 1.5 x 10-3 mol of sec- Buli. a) What is the expected number average chain length? (5 pts) b) What is the expected number average chain length if the efficiency of the initiator is 80%? (10 pts) c) At 75% conversion, 0.5 x 10-3 mol of water is added and the reaction continues. What is...

What type of polymerization is required to produce the polymer
below? Describe brief sequence of steps you would use (including
monomers used and order of processing) to achieve the desired
polymer.
There's anionic polymerization of styrene, there's cationic
polymerization, etc. I think anionic may help the most so I
provided that. But no idea. Or forming a graft copolymer?
What would be the number-average molecular weight of polystyrene obtained at the completion of an anionic (i.e., “living”) polymerization in which 0.01 g of n-butyllithium and 10 g of styrene monomer are used? The molecular weight of butyllithium and styrene are 64.06 and 104.12, respectively.
4. What monomer would you start with to make the polymer shown?
Would the polymer be made more effectively using a cationic or an
anionic polymerization?

2) You are studying actin polymerization in a solution. You perform an experiment where you add free actin, and wait a sufficiently long time. You notice that at some concentration of added actin, increasing the concentration of actin beyond that point increases the average actin filament mass in grams/mL A) The point at which actin filament mass increases is the critical concentration B) dPol/dt=0, so free actin concentration is the same across the entire range of added concentrations. C) Above...
In the lab, you will need to perform serial dilutions. What would be the concentration of the new solution made if you took 2.50 mL of a 0.10 M Cu(2+) solution and diluted it to 10.00 mL?
provide reactants/solvents/reagents
not sure what additional info would be needed, just
need the reactants to get to the final product, it's not from a
book, but a worksheet.
