A convenient method is described for the synthesis of ABA triblock copolymers having a high vinyl polyisoprene as center block and poly(methyl methacrylate) as end blocks. Dynamic mechanical properties of these copolymers as a function of temperature are compared for different compositions (100%, 85%, 70%, 60%, 50%, and 30% of rubber) using solvent‐casting methods. Since the morphology is dependent on the method of preparation of the samples, five solvents of different solubility parameters were tested for the same copolymer (i.e., 70% polyisoprene by weight) to show their influence on mechanical behavior.
