采用WCl6－ArOH／Et2AlCl（ArOH：2，6-二叔丁基对甲苯酚）催化体系进行了双环戊二烯的开环歧化聚合反应，考察了单体纯度以及催化体系支载化对聚合反应和合成聚合物性能的影响。在极限聚合浓度下，研究了单体与主、助催化剂摩尔比等因素对聚合反应及合成聚合物性能的影响。实验结果表明：单体纯度越高所得聚合物的机械性能越好；催化体系经聚合物支载化后能显著提高催化体系的催化聚合活性及合成聚合物的机械性能。
Abstract：Dicyclopentadiene (DCPD) was polymerized by ring-opening metathesis polymerization (ROMP) using the catalytic system of WC16-ArOH/Et2AlCl. The experimental results show that the yields and mechanical properties of synthesized polymers decrease with the decrease of DCPD's purity. The Catalyst dosage has an influene on ROMP of DCPD. The mechanical properties of synthesized polymers decrease with the decrease of catalyst dosage. Polydicyclopentadiene synthesized by using the Polymer-supported catalytic system possesses better mechanical properties than that synthesized by unsupported catalytic system.
