WebRecently, we demonstrated a water-based emulsion polymerization method (i.e. the temperature directed morphology transformation, TDMT, method[12-14]) to produce tadpole nanostructures directly in water facilitated by a thermoresponsive block when combined with the solvent swelling-induced technique. WebThe degree of polymerization is given by: DP = N p / (N 0 - N c) = N p / (N 0 - 0.65 N 0) = N p / 0.35 N 0 = 0.35 / (1-0.65) = 1. This means that each propagating chain on average terminates in one polymer molecule. To find the number of initiator fragments and polymer molecules terminated by coupling and disproportionation, we need to use the ...
