Segmented polyurethanes based on hexamethylene-diisocyanate, aliphatic polycarbonate diol and 1,4-butanediol as chain extender were prepared in a bulk by one-step procedure. The structure of elastomeric materials obtained in the form of films and sheets was varied either by polycarbonate diol type or chain extender content. The organically modified particles of montmorillonite and bentonite were used as reinforcing fillers. The glass transition temperatures of prepared hybrid materials were determined by modulated differential scanning calorimetry, MDSC. Promising thermal stability of obtained materials has been studied by thermogravimetry coupled with DSC.
