Abstract New thermoplastic elastomers have been prepared from the blends of metallocene-based polyolefins (Engage) with low-density polyethylene (LDPE), and ethylene-vinyl acetate copolymers (EVA) of different grades with LDPE by electron beam modification. Structural changes of these blends with or without sensitizer in presence of irradiation have been evaluated by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). Scanning electron microscopy (SEM) in conjunction with atomic force microscopy (AFM) indicate the soft rubber domain in the continuous plastic matrix. Significant improvements of mechanical, dynamic mechanical and set properties have been obtained by electron beam modification, retaining its reprocessibility characteristics. Effects of ditrimethylol propane tetraacrylate (DTMPTA) as radiation sensitizer have also been evaluated from the mechanical, dynamic mechanical properties and reprocessibility.

Irradiation effects on the properties of alumina trihydrate (ATH) / low-density polyethylene (LDPE)/ ethylene vinyl acetate (EVA) / calcium stearate (CS) have been studied and confirmed that EVA and CS addition to the polymeric blends have improved the mechanical properties. ATH addition increased the cross-linking density and improved the blend reinforcing factor but deteriorated the blend mechanical properties. CS addition made ease the ATH dispersion inside polymer matrix. CS addition optimum value in blends was 3 phr and CS addition above 3 phr value deteriorated the blends mechanical properties.
