telomerization

https://doi.org/10.1351/goldbook.T06260

The formation of an addition oligomer, having uniform end groups X' ... 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' = CCl₃, X'' = Br), where Cl₃C· radicals are formed in the initiation step to produce Cl₃C[CH₂CHPh]_nBr, with n greater than 1 and often less than ca. 10:
