摘要：

The effects of EPDM admixture, mixing conditions and additional stabilization on the phase structure and impact strength of low-density polyethylene/isotactic polypropylene (LDPE/PP) blends were studied. It was proved that EPDM is localized at the interface between LDPE and PP phases. The admixture of 5% EPDM substantially increases impact strength of LDPE/PP blends at all the compositions. Higher intensity and longer time of mixing have a positive effect on the impact strength of the studied blends. For the blends with higher content of polypropylene it is necessary to prevent their degradation by additional stabilization.
