A living polymerization is carried out using 150 mmol of 4-chlorostyrene and 1.2 mmol of initiator. Calculate the degree of polymerization (Pn) and number average molecular weight (Mn) of the polymer obtained if the conversion was 100%.
Homework Answers
Molecular weight of 4-chlorostyrene = 138.59 g . mol-1
number average molecular weight (Mn) = 
Mi Ni /
Ni
Degree of polymerization (Pn) = number average molecular weight (Mn) / average molecular weight of repeat unit
=> Pn = number average molecular weight (Mn ) / 138.59 g . mol-1

For polymerization of styrene in tetrahydrofuran at 25°C using sodium naphthalide initiator, the rate coefficient for propagation is 550 dm^3 mol^-1 s^-1. If the initial mass concentration of styrene is 156 g dm^-3 and that of sodium naphthalide is 3.02x10^-2 g dm^-3, calculate the initial rate of polymerization and, for complete converison of the styrene, the number-average molar mass of polystyrene formed. Comment upon the expected value of molar mass dispersity (Mw/Mn) and the stereoregularity of the polystyrene produced. Assume:...
