Title:
POLYLACTIC ACID-CONTAINING BLOCK COPOLYMER-GRAFTED POLYROTAXANE AND RESIN COMPOSITION INCLUDING THE BLOCK COPOLYMER-GRAFTED POLYROTAXANE
Document Type and Number:
Japanese Patent JP2014084414
Kind Code:
A
Abstract:
To provide a polylactic acid-based material satisfying both impact resistance and flexibility without sacrificing heat resistance.
Provided is a polylactic acid-containing block copolymer-grafted polyrotaxane comprising a cyclic molecule clathrated by a linear molecule in a state where a void portion thereof is being skewered by the latter and a blocking group possessed by each of both terminals of the linear molecule so as to prevent dislodgment of the cyclic molecule therefrom, wherein the cyclic molecule possesses graft chains including a first graft chain and a second graft chain in this order; the first graft chain is a flexible polymer, whereas the second graft chain is polylactic acid.
