Controlled Radical Polymerization
Serves as a key Chain Transfer Agent (CTA) in Reversible Addition-Fragmentation chain Transfer (RAFT) polymerisation. It is especially suitable for polymerising methacrylate and methacrylamide monomers, enabling precise control over polymer architecture.
Functional Polymer Synthesis
The presence of an alkyne group allows for post-polymerisation modification via click chemistry, enabling the synthesis of complex polymer architectures and functionalised materials. Its photo-sensitive moiety offers further control over polymer chain cleavage.
Materials Science Research
Its unique combination of RAFT capabilities and clickable functionality makes it a valuable reagent for researchers in materials science developing novel polymers with tailored properties.
