b

the concentration styryl-tempo alkoxyamine required to produce polystyrene with a number average degree of polymerization of 100 at 60% converision; and b: the time required for the polymerizationto attain this conversion, taking into the persistent radical effect. the values at 125 degree cfor the parameters required in the kinetetics are"

rate coefficient for propagation ^3mol^-1s^-1d ^-1s^-1

rate coefficient for termination .6*10^8 dm^3mole^-1s^-1

equilibrium constant knmp= 2.1*10^-11 mol dm^-3

density of styrene .84 gcm^-3
