Abstract

Polyethylene has become the most important polyoleﬁn plastic with excellent mechanical properties, processing properties and chemical stability. It is used in the production of film, packaging and pipe. However, the non-polar property and low rigidity limit its application in certain ﬁelds. The new progress of chemical and physical modiﬁcation upon polyethylene are reviewed. The former includes graft modification, chlorination, copolymerization modification, crosslinking modification, chlorosulfonation modification and plasma modification. There are different methods of polyethylene production which include high-, medium- and low-pressure polyethylene. All three methods had their own beneﬁts and shortcomings which coexist in the industry.
