This study presents the synthesis and physical characterization of a series of structurally well- defined star-shaped poly (lactic acids). Polymer stars are prepared from a series of multifunctional alcohol cores including flexible polyols pentaerythritol and dipentaerythritol (four-armed and six-armed cores, respectively) and rigid substituted arenes tri (hydroxymethyl) benzene and hexa (hydroxymethyl) benzene. Utilizing a tin (II) octanoate ...
