Abstract

Chain-length-dependent termination rate coefficients of the bulk free-radical polymerization of styrene at 80 °C are determined by combining online polymerization rate measurements (DSC) with living RAFT polymerizations. Full k_t versus chain-length plots were obtained indicating a high k_t value for short chains (2 × 10⁹ L · mol^-1 · s^-1) and a weak chain-length dependence between 10 and 100 monomer units, quantified by an exponent of -0.14 in the corresponding power law (k_t^i,i) = k_t⁰ · P^-b.
