Abstract

The behaviour of some microstructured polymers obtained under dynamic vulcanization conditions in a pilot reactor containing a mixture of EPDM rubber and high density polyethylene (HDPE) at various elastomer/plastic polymer weight ratios in the presence of sulphur (system I) and peroxides (system II) as cross-linking agents was studied. We correlated the swelling in the solvent and the thermal properties with the chemical composition and microstructure of the polymer. The results are very useful in choosing the appropriate utilisation of these polymer mixtures in various industrial domains.
