The formation of an addition oligomer, having uniform end groups X'
, by a chain reaction in which a chain transfer limits the length of the polymer ('telomer') produced. An example is the polymerization of styrene in bromotrichloromethane solution (X'
), where Cl3C·
radicals are formed in the initiation step to produce Cl3C[CH2CHPh]nBr
, with n greater than 1 and often less than ca
