Well-Defined Amylose Acetate-<i>graft</i>-polylactide Graft Polymers as Compatibilizers for Renewable Polymer Blends.

ABSTRACT: Regioselectively substituted amylose acetate-graft-polylactide (AmAc-g-PLA) graft polymers were synthesized via grafting-to "click" reaction between C6-azide functionalized AmAc and alkyne-terminated PLA. Alkyne-terminated PLA synthesized through organocatalytic ring-opening polymerization (ROP) permitted control over graft degree of polymerization (DP) and stereochemistry, while azide functionalized AmAc with tailorable C6-azide degree of substitution (DS) allowed graft density control. This describes the first synthesis of polysaccharide-based graft polymers with exclusive C6 grafting and controllable topology. Thermal analysis indicates that glass transition temperatures (T_g) of AmAc and PLA segments are affected after grafting-to coupling, with poly(l-la
