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...

Isotactic Polypropylene (C3H6 MW=42g/mol), a thermo plastic is
synthesized using bulk polymerization. For a monodisperse sample
(PDI=1) the bigger molecule(higher degree of polymerization)
contain the same total mass of the polymer sample than the smaller
molecules(lower degree of polymerization). For a polydisperse
sample the MW fractions do not contain the same mass.
Flexlife is the capability of polymeric material to withstand
repeated bending without fracture. The Z average MW (Mz) is a
measure of flexlofe as well as the predominance...
