Abstract
Atom transfer radical polymn. (ATRP) is a relatively new technique that allows large control over the molar mass distribution of the resulting polymer. In the present paper we aim to obtain information related to the mechanism of ATRP through copolymn. Three different techniques are employed to obtain the exptl. data required. On line ESR spectroscopy is used to measure Cu(II) concn. during the reaction, UV/Vis spectroscopy is used to monitor the complexes, and reactivity ratios of a classical free radical copolymn. are compared with those of an ATRP expt. Reactivity ratios indicate that the propagating species are radicals. Other phenomena will be discussed that raise doubt on the free diffusion of the propagating radicals
