摘要: A method of direct switching from anionic polymerization into RAFT-based was developed. The transformation involved in situ addition living carbanionic species, end-capped with DPE, toward CS2 and subsequent reaction alkyl bromides, resulting macro-RAFT agents (macro-CTAs). macro-CTAs were used to mediate RAFT (functional) vinyl monomers. These processes performed a continuous way without isolation the intermediate. Diblock or ABA-type triblock copolymers, composed polydiene segment functional acrylate (2-hydroxyethyl acrylate, HEA) acrylamide (N-isopropylacrylamide, NIPAM), synthesized by mediated PI macro-CTAs. successful preparation block copolymers demonstrated self-assembly amphiphilic diblock copolymer PI75-b-PNIPAM199 water (selective solvent for PNIPAM) heptane PI). obtained are cleavable homopolymer components due prese...
