「東北ポリマー懇話会山形地区講演会」

題目：　Synthesis and Properties of Well-Defined Multicomponent Star and Graft Copolymers by メLivingモ/Controlled Polymerization

講師：　Prof. Youliang Zhao (College of Chemistry, Chemical Engineering and Materials Science, Soochow University)

Abstract:

Functional star-shaped and graft copolymers normally exhibit more complex microphase separation structures and self-assembly behaviors than their linear analogues due to their branched chain architectures, and thus they are of intriguing properties and applications in many fields involving nanoscience and biotechnology.

Our study aims at synthesis, characterization, and potential application of complex macromolecular architectures involving dendrimers, hyperbranched polymers, and star / graft copolymers.

Three parts of contents will be presented in this talk, namely, synthesis of multiarm stars via controlled radical polymerization and ring-opening polymerization (a), modular synthesis of miktoarm stars and H-shaped copolymers via linking chemistry and controlled polymerization (b), and facile synthesis of miktoarm stars and comblike copolymers based on maleimide-styrene copolymerization system (c). Although our researches are primarily focused on synthetic methodology, some basic physicochemical properties such as microphase separation and self-assembly behaviors of polymers, and drug-loading and controlled release properties of copolymer aggregates were also investigated. Moreover, our recent research revealed that the introduction of cleavable linkages into functional copolymers could allow more promising potential in versatile topological conversions and smart drug delivery systems.
