摘要: Advances in controlled radical polymerization (CRP) have facilitated access to well-defined polymers with molecular weight, topology, and functionality. However, despite the benefits afforded by many CRP techniques, control over these key polymer attributes often comes at expense of rate. One method proposed for accelerating chemical synthesis is microwave heating. This review highlights recent examples heating being applied during reversible addition-fragmentation chain transfer (RAFT) polymerization. In addition successfully leading homopolymers from a variety monomers, block copolymers also been prepared microwave-assisted RAFT, which suggests that high rates observed do not necessarily lead significant end group loss termination. Despite debate regarding origin rate enhancement reactions, reports included herein provide insight into mechanisms functional can be an accelerated fashion.
