用于润滑油改性的乙丙共聚物的合成 蔡小平 邹向阳 张红江 廖凤英 谢妤 摘要:以V-A1体系为催化剂,己烷为溶剂,采用分子量调节剂合成出了组
成、结构、分子量及分子量分布与美国Exxon-8921基本相同的润滑油改性用乙丙共聚物。
经应用评定证明其综合性能好,适合调制各种中、高档多级内燃机油,并在2万t
/aEPDM生产装置上实现工业化。 Synthesis of
ethylene propylene copolymer used as CAI Xiao-ping,ZOU
Xiang-yang,ZHANG Hong-jiang,LIAO Feng-ying,XIE Yu ABSTRACT Ethylene propylene
copolymer used as viscosity index improver for lubri cating oil was synthesized by using
V-Al as catalyst,hexane as solvent and ETCA as molecular weight adjusting agent,the
product is almost the same as that of E xxon-8921 in composition,micro structure,molecular
weight and molecular weight d istribution.It has been indicated by applying examinations
that the product has excellent comprehensive properties and is suited for making virous
degrades of multisage internal combustion engine oils.The technology based on which has
bee n used in the 20,000t/a EPDM commercial plant. 基金项目:中国石油天然气集团公司资助项目(990806-11) 参考文献: 收稿日期:2000-04-28 |
