Synthesis and water absorption of galactose-containing amphiphilic triblock copolymers based on PLAs†
Abstract
Well-defined amphiphilic triblock copolymers PMAGP-b-PLA-b-PMAGP with varied compositions and molecular weights were obtained via a four-step procedure. The hydrophilicity and water absorption increase with an increase of the PMAGP chain length. The presence of active hydroxyl groups was confirmed by a dyeing procedure.
