<P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition which can impart effects, e.g., of improving the fluidity (moldability) and mechanical strength (particularly, weld strength) of an olefinic resin, and further, improving dimensional stability, by blending a dendritic polyester having excellent heat resistance and dispersibility into the olefinic resin. <P>SOLUTION: The thermoplastic resin composition is obtained by blending a dispersing auxiliary agent (C) as an organic compound having a functional group and/or as an ionomer into a dendritic polyester resin (B) exhibiting melt mesomorphism, which includes: at least one structural unit selected from the olefinic resin (A) and an aromatic oxycarbonyl unit (P), an aromatic and/or aliphatic dioxy unit (Q) and an aromatic dicarbonyl unit (R); and organic residue (D) of three or more functions, wherein the content of the D lies in the range of 7.5 to 50 mol% based on the whole monomer composing the dendritic polyester. <P>COPYRIGHT: (C)2012,JPO&INPIT |
