Abstract
This paper presents the maleinization study of linear styrene-butadiene block-copolymers carried out in solution by radical mechanism. The vinyl microstructure effect of the polybutadiene block on the kinetics reaction was established and the physical and mechanical properties were correlated with the maleinization degree of the elastomers. Keywords: styrene-butadiene block-copolymers, maleic anhydride, functionalized block-copolymers
