摘　　要：采用熔融共混-传递模压成型方法制备了不同比例的PPS/PES共混材料,运用热重分析和示差扫描量热分析对其力学性能和热力学行为进行了研究.研究结果表明,PES能有效改善PPS的拉伸和弯曲性能,能提高其抗冲击性能;PPS/PES共混体系是具有部分相容性的多相共混体系,且其相容性的好坏与PES含量密切相关;PES的加入提高了PPS的玻璃化温度和熔点,从而有利于提高合金材料的使用温度.PPS/PES blends of different proportion were prepared by physical blending –transfer compression molding.The mechanical property and thermodynamic behavior of the blend have been studied by means of DSC and TG.Results show that the tensile and bending properties of PPS have been apparently improved with the addition of PES,and the anti-impacting performance has also been enhanced.The PPS/PES blend is a multiple-phase system of partly compatibility,and its compatibility is closely related to the content of PES.The glass state temperature and melting point of the blends have been raised so that they can be used at a higher temperature.
