A chitosan derivative, methyl ether-terminated poly(ethylene oxide)-4-methoxycinnamolyphthaloylchitosan (PCPLC) was prepared, characterized and self-assembled into nanoparticles. Encapsulation of ascorbyl palmitate (AP) into PCPLC gave 6890.98 nm particles with encapsulation efficiency of 84% at 56% drug loading. The encapsulated AP showed significant
