Compatibilization of polyolefins waste based blends by reactive modifiers with anhydride

or oxazoline functional groups

Polimery 2007, No 5, 371


Summary

The effects of reactive modifiers with anhydride or oxazoline functional groups on the morphology and the mechanical properties of polyolefins waste based blends prepared by melt blending have been studied. The materials were first subjected to morphological analyses by scanning electron microscopy (SEM). The modifiers act as compatibilizers in the structurally heterogeneous blends. Tensile tests showed that the blends had significantly improved elongation and impact strength over their unmodified analogues. Improvements in tensile and impact properties depend on the blend composition and the modifier used.


Key words: recycling, polyolefins, blends, reactive modifiers, reactive extrusion
