A detailed review is given on experimental techniques in free‐radical polymerization kinetics. Besides the wellknown and familiar methods for the determination of monomer conversion (rate of polymerization) and initiator decomposition (rate of initiation) some further possibilities of getting more detailed information about the reaction system are shortly discussed (e.g. detection of end‐groups in the polymer, determination of molecular weight distributions).
Special emphasis is given to some newer techniques with their abilities of automatic acquisition and treatment of data with the help of microprocessors.
Problems associated with calibration procedures as well as error sources are discussed. Techniques for both steady state and non‐stationary polymerization experiments are reported.
