A thermoplastic polymer having polar groups which comprises a thermoplastic polymer grafting-modified with at least one of unsaturated compounds having a polar group which are represented by the following general formula (I): A-X-R2-(Y)p-R1 (wherein A represents a group containing a double bond; X and Y each represents -COO-, -OCO-, -CO-, -O-, etc.; R2 represents either a divalent group containing carbon or a single bond; p is 0 or 1; R1 represents a polar group selected among carboxylic anhydride groups, epoxy, etc. or alkyl, cycloalkyl, or aryl each containing a polar group; and the chain connecting the double bond in A to the polar group in R1 is composed of six or more atoms). |
