The competitive reactions of cyanoisopropyl radicals with the mixed monomers styrene and acrylonitrile have been investigated using the nitroxide radical trapping technique. When the trap concentration is kept low, second, third, and even fourth generation (in terms of successive monomer addition) c
## Abstract Literature data are summarized for the chainβlengthβdependence of the termination rate coefficient in dilute solution freeβradical polymerizations. In essence such experiments have yielded two parameter values: the rate coefficient for termination between monomeric free radicals, __k__,
