Mechanical characterization of structural evolution in modified unsaturated polyester resins

Polymer Bulletin Aims and scope Submit manuscript

Summary

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 %.
