Abstract The purpose was to develop a procedure to synthesize copolymer incorporating flexible polyisoprene blocks and rigid polycarbonate blocks, to obtain thermoplastic elastomer characteristics. The choice was directed towards poly(isoprene‐ b ‐carbonate) structures by using a condensation mechanism consisting to create carbonate functions by reaction between an organic dihalide and a diol carried out in presence of potassium carbonate, and by using hydroxytelechelic polyisoprenes as reagents. Polycarbonates of various structures were synthesized, followed by that of the required poly(isoprene‐ b ‐carbonate)s. The synthetic procedure thus developed has the advantage to allow a control of the structure and the composition of the copolymer according to the nature and the proportions of the reagents involved. © 2007 Wiley Periodicals, Inc.
