Abstract

We report (i) synthesis of novel graft copolymers of a α-CD/PEG polyrotaxane (PRX) backbone and enantiomeric PLA side chains, PRX-g-PLLA and PRX-g-PDLA, (ii) selective stereocomplex formation on a movable PRX in the bulk state, and (iii) preparation of soft materials with continuous anisotropic phases by blending of the L- and D-isomers.
