摘要用单螺杆挤出机对尼龙6与化学改性聚丙烯（MPP）进行了全组分范围的熔融共混。测量了共混体系的拉伸、弯曲和冲击性能。结果发现，MPP作为第二组分对所得共混物的性能具有深远的影响。MPP的加入降低了拉伸强度和弯曲模量，而拉伸模量和弯曲强度在中间组成处经历最小值。只有当尼龙6是基础树脂和MPP用作添加剂时，才能获得冲击强度的改善。用扫描电子显微镜研究了共混物的微观结构。
Abstract Melt blending of nylon 6 with chemically modified polypropylene (MPP) is carried out with a single-screw extruder over the whole range of compositions. The tensile, flexural, and impact properties are measured for the blend system. It is found that the MPP used as the second component has a profound effect upon the properties of the resulting blends. The addition of MPP decreases the tensile strength and flexural modulus whereas tensile modulus and flexural strength go through a minimum at the intermediate compositions. An improvement in impact strength is obtained only when nylon 6 is the basic resin and MPP is used as an additive. Microstructures of polyblends are studied by scanning electron microscopy.
