The effects of internal structure, degree of polymerization, crystallinity and molecular orientation upon the friction and wear properties of plastics against steel were studied in this article.1) The friction coefficients of polyethylene (PE) and polyacetal (POM) increase with the increasing of molecular weight. The sliding wear rate (Vs) of POM increases with the increasing of molecular weight.2) The friction coefficients of PE, polyethylene terephthalate (PET) and polytetrafluoroethylene (PTFE) decrease with the increasing of crystallinity degree. The Vs of PE and POM decrease with the increasing of crystalinity degree, that Vs of PTFE increases with the increasing of crystalinity degree.3) The friction coefficients of PE, PET and PTFE for the orientated direction decrease with the increasing of the orientated direction and degree of oriention.
