Abstract
It has been demonstrated experimentally, that Plastic Energy Dissipation (PED) is the most important heating/melting mechanism, especially in the initial stage of heating of compacted solid polymer particulates in polymer compounding equipment, where forced particulate deformation takes place. Our previous work has also found that the melting of multi-component polymer blends is totally different from that of the individual blend component. The difference has been correlated to the different PED response of individual blend components in the deformation of polymer blends. In this work, we study the PED behavior of model polymer blends (PE/PS) at different compositions as well as the effect of a compatibilizer on the blend PED. The Specific Mechanical Energy (SME) input associated with PED of both uncompatibilized polymer blends and compatibilized polymer blends during uniaxial compressive deformation is calculated and compared.
