摘要：

The solution and solid-state properties of hybrid linear-dendritic polyether copolymers are investigated by size-exclusion chromatography with coupled viscometric detection, polarized light microscopy, and X-ray analysis. The results obtained show that the block copolymers are able to form mono- and multimolecular micelles depending on the dendrimer generation and the concentration in methanol/water (good solvent for the linear blocks). Only monomolecular micelles are observed in THF (good solvent for the dendritic blocks). The linear blocks are able to crystallize in spherulites, axialites, or unique dendritic structures depending on the overall composition of the copolymers and the solvent used.
