    • The present invention provides a modified polyolefin type polymer having one structural unit having a glycidyl group represented by the following general formula (I) per 2-1,000 repeating units of olefin: ##STR1## (In the formula, Ar represents an aromatic hydrocarbon group 6-23 in carbon number having at least one glycidyloxy group, and R represents hydrogen atom or methyl group.), its manufacturing method and a resin composition containing the aforementioned modified polyolefin polymer. The polyolefin type polymer of the present invention is excellent not only in mechanical properties, heat resistance and resistance to oil, but also in dyeability, adhesiveness, antistatic property. It enables blending and conversion into alloys for its outstanding affinity with other resins.
