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.
