In this work, we would like to present the morphological and rheological characterization of model butadiene-dimethylsiloxane block copolymers (PB-b-PDMS). These model block copolymers were obtained by anionic polymerization (high vacuum techniques) using 1,3-butadiene and hexamethyl(ciclotrisiloxane) monomers, sec-butyl lithium as initiator, and sequential addition.
