This investigation reports preparation of tailor-made copolymer of FMA by RAFT polymerization and study of its self-healing characteristics. In this case the copolymers of FMA and butyl methacrylate (BMA) were prepared by RAFT polymerization using 4-cyano-4-[(dodecylsulfanylthiocarbonyl)sulfanyl] pentanoic acid (CDTSP) as a RAFT reagent. Here BMA was used as the comonomer, as its glass transition temperature (Tg) is low (~25 C) i.e at ambient temperature. The tailor-made RAFT copolymer was reacted with bismaleimide to prepare thermally amendable polymer by the use of DA reaction. The DA cross-linked polymer was characterized by FT-IR, NMR, DSC and depth sensing nano indentation (DSI) analysis. The self-healing characteristics of the polymer were analyzed bySEM analysis.
