摘　　要：以乙烯醋酸乙烯共聚物接枝马来酸酐(EVA-g-MAH)做增容剂,采用双螺杆挤出机熔融共混法制备了热塑性聚氨酯(TPU)与高密度聚乙烯(HDPE)的共混物。研究了真空和空气中γ辐照对共混物力学性能的影响,结果表明适当剂量的辐照改善了TPU/EVA-g-MAH/HDPE的力学性能。The blends of TPU and HDPE were extruded with a twin-screw extruder through melting mix with EVA-g-MAH as the compatibilizer. The effects of γ-irradiation in vacuum and air on the mechanical properties were studied. The result showed that proper dose of γ-irradiation improves the mechanical properties of TPU/EVA-g-MAH/HDPE.
