The effect of compatibilization in reactive processing low density

polyethylene/polyamide 6/EPDM blends (in English)

Polimery 2006, No 9, 656



DOI: dx.doi.org/10.14314/polimery.2006.656


Summary

The compatibilizing effect of functionalized low density polyethylene (PE-LD) on PE-LD/polyamide 6 (PA6)/ethylene-propylene-diene terpolimer (EPDM) ternary blends has been studied. Compatibility was evaluated by means of differential scanning calorimetry, which was used also for studying the melting and crystallization phenomena. Torque-time measurements were performed in order to determine the processing behavior. The functionalized PE-LD modify the processing behavior, the crystallinity degree of PE-LD and PA6 and impact properties of the studied blends. These effects result from chemical reactions between functional groups of compatibilizing agents and the end groups of polyamide.


Key words: low density polyethylene, polyamide 6, functionalized PE-LD, miscibility, compatibilization, processing behavior, crystallinity degree, impact strength
