2003—2004年聚烯烃新品种的进展

Advances of New Polyolefinic Products During 2003-2004

介绍了2003—2004年国外一些大型石化企业陆续推出的聚烯烃新品种,包括含有等规丙烯链链段结晶的聚烯烃热塑性弹性体、新型柔韧丙烯共聚物、第二代聚1-丁烯、用茂金属催化剂制得的性能更优异的管材用双峰相对分子质量分布聚乙烯及新一代无规共聚聚丙烯(PPR)管材专用料等,并从这些公司研究开发新品种的过程所得到的启示,联系实际,提出自已的看法。

During 2003-2004 several new kinds of polyolefinic products have been introduced into market by large petrochemical companies abroad, such as polyolefin thermoplastic elastomers with isotactic propylene crystallinity, novel soft and tough propylene copolymers, second-generation poly(1-butene), advanced higher performance pipe-grade bimodal polyethylene made with metallocene catalyst and next-generation random polypropylene (PPR) pipe compounds. Advances of these materials were briefly reviewed. Suggestions to be learned from the achievements of these companies were proposed.
