摘要: Composites of polyethylene, ethylene propylene diene rubber (EPDM), and calcium carbonate are milled analyzed by solid state dynamic mechanical spectroscopy. The torsion pendulum measurements show that the multicomponent composites exhibit complex viscoelastic behavior. In polyethylene carbonate, experimentally observed modulus enhancement is greater than expected from properties constituent materials, assuming well-dispersed inclusions. rubber, interactions with filler surface significant. Specifically, maleic anhydride modification EPDM results in rubber-filler drastically influence composite. a morphology more around particles thus an enhanced glass transition peak. interaction has been attributed to salt formation at surface. was also detected proton nuclear magnetic resonance (NMR) relaxation experiments. Treatment gamma-aminopropyltriethoxysilane (γ-APS) or gamma-methacryloxypropyltrimethoxysilane (γ-MPS) significant on properties.
