Abstract

he 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 reactivity 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) with respect to ST (r(ST) = 0.47). ST/Boc-AMST copolymers characterized by a "quasi" random distribution of monomeric units with tendency to alternating placement, were thus obtained.
