摘　　要：以MI=26 g/10min的LLDPE与MI=7 g/10min的LDPE按照1∶1混合,作为载体,制成浓度为20%的蓝色母粒。研究该体系的加工流变性能、母粒的着色性能、分散性能以及制品的力学性能,并与以低分子量聚乙烯蜡作为分散剂的传统体系进行对比。A 1：1 blend of LLDPE （M1 = 26 g/10min） and LDPE （MI = 7 g/10min） as the carrier was prepared for the manufacture of the blue eolour masterbatch samples containing 20 % blue pigment. A low molecular weight polyethylene was used as a dispersing agent. Its effects in the system were studied on the rheological characteristics, colouring properties, and dispersion and mechanical properties of the final end-products containing the masterbatches.
