Abstract: The recent progress in the immobilization of non-metallocene olefin polymerization catalyst is reviewed. According to the different types of supports，this paper introduces the preparation and characterization of supported catalyst. The influence of the immobilization methods，polymerization temperature，the amount and type of co-catalyst，polymerization pressure and the effect of hydrogen on the behavior of supported catalysts in olefin polymerization are discussed. Moreover，the effects of such conditions mentioned above on the properties of the obtained polymers，such as molecular weight，molecular weight distribution，melting temperature，morphology，etc. are summarized.
