Abstract
Official abstract text for this publication.
The present invention aims to provide a polyester resin composition capable of producing a molded article having excellent stretchability. The present invention also aims to provide a molded article including the polyester resin composition. The present invention relates to a polyester resin composition including: a polyester resin; and a polyrotaxane that has a cyclic molecule, a linear molecule threading through a cavity of the cyclic molecule in a skewered manner, and capping groups capping both ends of the linear molecule.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polyester resin composition comprising: a polyester resin; and a polyrotaxane that has a cyclic molecule, a linear molecule threading through a cavity of the cyclic molecule in a skewered manner, and capping groups capping both ends of the linear molecule, wherein a polycaprolactone chain is introduced to the cyclic molecule, the polycaprolactone chain has a carboxyl group as a substituent at its terminal, and the polyrotaxane contains polyethylene glycol as the linear molecule and a molecule derived from α-cyclodextrin as the cyclic molecule. 2. The polyester resin composition according to claim 1 , wherein the polyester resin contains a polylactic acid resin and/or a polyglycolic acid resin. 3. A molded article comprising the polyester resin composition according to claim 1 .
