The aim of this paper is to report on structural characterization of unsaturated polyester resins modified by grafting elastomer. D.S.C. tests, dynamic mechanical tests and work-hardening rate measurements have been performed. The latter can be regarded as a very sensitive micro mechanical probe of thermoset structure : the work-hardening rate K exhibits appreciable variations with the elastomer wt %.
