The preparation and characterization of styrene (ST)Boc-p-aminostyrene (Boc
-AMST) copolymers, obtained by free radical polymerization in solution, are
reported. The preparation of Boc-AMST as well as the evaluation of the rea
ctivity ratios of ST and Boc-AMST by Kelen and Tudos method constitute the
focal aspects of the present contribution. The evaluation of the reactivity
ratios substantiated a higher reactivity of Boc-AMST (r(BocAMST) = 0.96) w
ith respect to ST (r(ST) = 0.47). ST/Boc-AMST copolymers characterized by a
"quasi" random distribution of monomeric units with tendency to alternatin
g placement, were thus obtained. (C) 2000 John Wiley & Sons, Inc.
