【摘要】 采用双金属复合催化剂制备出了宽或双峰分子量分布的高密度聚乙烯(HDPE),并对所合成出的聚合物进行了结晶行为分析、分子量及分子量分布测试。结果表明:用双金属复合催化剂法制备的HDPE的力学性能优于传统方法。更多还原

【Abstract】 High density polyethylene (HDPE) with wide or bimodal molecular weight distribution was prepared by using bimetallic composite catalysts. The crystallographic behaviour, molecular weight and molecular weight distribution of the polymer so synthesized were analyzed. The results showed that the mechanical property of the polymer was superior to those prepared with conventional process.更多还原
