Dendritic Polymer, Method for Producing the Same, and Thermoplastic Resin Composition |
摘要 |
The present invention is directed to a hyperbranched-polyester comprising at least one kind of a structural unit selected from an aromatic oxycarbonyl unit (P), aromatic and/or aliphatic dioxy units (Q), and an aromatic dicarboxy unit (R), and a trifunctional or higher polyfunctional organic residue (B), wherein the content of B is within a range from 7.5 to 50 mol % based on entire monomers constituting the hyperbranched-polyester. The present invention provides a hyperbranched-polyester which can remarkably improve thin-wall flowability, stiffness and gas barrier property by blending with a thermoplastic resin, and a thermoplastic resin composition blended with the same.
