摘　　要：研究了PC/PA合金的力学性能、流变性能和耐油性能。结果表明 ,自制增容剂P与SMA协同使用对PC/PA共混体系有较好的增容作用 ,增容后合金的冲击强度大幅度提高 ,同时合金仍保持较高的拉伸强度和弯曲强度。PC/PA/SMA/P合金熔体的表观粘度随剪切速率提高而下降 ,加工流动性得到改善。PC/PA/SMA/P合金具有较好的耐油性。Mechanical properties,rheological behavior and oil-resistance of PC/PA alloys were studied.Results show that the compatibility between PC and PA was greatly improved when another compatibilizer P was added to the system to work with SMA synergistically.The impact strength of the alloy was increased highly while the good tensile strength and the bending strength were maintained.Apparent viscosity of PC/PA/SMA/P was decreased as the shear rate went up which implied that the rheological property of the alloy was improved.Furthermore,oil-resistance of PC/PA/SMA/P alloy was good.
