摘　　要：对聚烯烃类的结晶聚合物 ,在普通的注塑和挤出成型条件下 ,通常得到具有球晶结构的制品 ,不能充分地展示高聚物的力学潜能。本研究应用一些新的成型技术 ,在制品中生成特殊的凝聚态结构 ,使得在不加入任何外增强相的情况下大幅度地提高制品的物理力学性能 ,由此可以看出成型技术、微观结构与制品性能之间的复杂关系。文中介绍的采用形态控制技术制备高性能注塑和挤出制品 。Crystalline polymers such as polyolefin, processed by conventional injection molding and extrusion always exhibit a spherulitic morphology, which precludes their potential mechanical properties. Some new processing technologies were employed to achieve high strength parts due to the formation of special crystalline morphology, without adding any reinforcements. The complicate relationships between processing technologies, microstructures and properties were reviewed accordingly. The technology of producing high performance injection and extrusion products with morphological controlling technology introduced in this paper had more theory and experience application value. We will make further study on morphological controlling technology.
