Abstract
The behaviour of some microstructured polymers obtained in dynamic conditions using a mixture (1:1) of EPDM (ethylene-propylene-dien monomer) rubber and high-density polyethylene (in the presence of sulphur as reticulating agent) was studied. The experiments consisted in determination of swelling by maintaining the polymeric composite materials in three organic solvents (benzene, p-xylene, carbon tetrachloride) and also in recording their IR spectra. The results are useful for selection of operating conditions during preparation and for choosing the appropriate utilization of polymeric products. Keywords: microstructural polymer, EPDM (ethylene-propylene-dien monomer) rubber, polyethylene, swelling, IR spectroscopy
