通过引入卤代醇类化合物制备了适用于乙烯淤浆聚合工艺的新型高性能Ziegler-Natta催化剂（简称GH催化剂）。采用分光光度计、扫描电子显微镜等表征了催化剂的组成、粒径和形态等；采用淤浆聚合法研究了催化剂的聚合性能，并与国产商业化催化剂（参比催化剂）进行了比较。结果表明：GH催化剂的活性达21.6?kg/g，聚乙烯堆密度达0.34?g/cm3，粒径≥75~830?μm的聚乙烯粉料质量占聚乙烯粉料总质量的97.9%，且GH催化剂的氢调敏感性和其催化乙烯与1-己烯共聚合的性能均优于参比催化剂。
通過引入滷代醇類化閤物製備瞭適用于乙烯淤漿聚閤工藝的新型高性能Ziegler-Natta催化劑（簡稱GH催化劑）。採用分光光度計、掃描電子顯微鏡等錶徵瞭催化劑的組成、粒徑和形態等；採用淤漿聚閤法研究瞭催化劑的聚閤性能，併與國產商業化催化劑（參比催化劑）進行瞭比較。結果錶明：GH催化劑的活性達21.6?kg/g，聚乙烯堆密度達0.34?g/cm3，粒徑≥75~830?μm的聚乙烯粉料質量佔聚乙烯粉料總質量的97.9%，且GH催化劑的氫調敏感性和其催化乙烯與1-己烯共聚閤的性能均優于參比催化劑。
