title: Novel "star anise"-like nano aggregate prepared by self-assembling of preformed microcrystals from branched crystalline-coil alternating multi-block copolymer.
abstract: Nano aggregates in aqueous medium with a novel "star anise"-like morphology were prepared from a branched alternating multi-block copolymer composed of 3-arm star-like hydrophobic poly(p-dioxanone) block and linear hydrophilic poly(ethylene glycol) block. The influence of block length on the morphology of the nano aggregate was investigated.
