macroinitiatorbased
Macroinitiator-based polymerization refers to a class of polymerization strategies in which a preformed polymer chain bearing reactive initiator functionality acts as the starting block for further polymer growth. In this approach, the macroinitiator provides a defined polymeric segment (the macroblock) and a callable initiation site that enables subsequent monomer polymerization to form block copolymers, graft copolymers, or branched architectures. The resulting materials combine the properties of the original polymer with those of the newly grown block or graft.
Typically, macroinitiators are prepared by functionalizing the chain end or side chains of a polymer so that
Applications of macroinitiator-based methods include the synthesis of block copolymers for nanostructured materials, thermoplastic elastomers, compatibilizers,
