Synthesis of hybrid inorganic/organic homopolymers via ATRP and RAFT: A practical comparison

  • The synthesis of hybrid inorganic/organic copolymers, using reversible deactivation radical polymerization (RDRP) techniques, has been an intensively studied research topic over recent years. A plethora of hybrid inorganic/organic copolymers were synthesized, including hybrid inorganic/organic block copolymers as well as random copolymers,[1–4] that showed great potential in fabricating hybrid (nano)materials with tailored properties [5]. Two widely employed RDRP techniques to prepare such hybrid inorganic/organic copolymers are atom transfer radical polymerization (ATRP) [1,2] and reversible addition-fragmentation chain transfer (RAFT) polymerization [3,4]. In order, to afford hybrid inorganic/organic copolymers with narrow dispersity, high conversions and precise structures, it is required to choose proper reaction conditions. Due to the importance of both ATRP and RAFT in the preparation of such hybrid polymers, we aim to compare both RDRP techniques by preparing 2-acetoxyethylThe synthesis of hybrid inorganic/organic copolymers, using reversible deactivation radical polymerization (RDRP) techniques, has been an intensively studied research topic over recent years.

Due to the importance of both ATRP and RAFT in the preparation of such hybrid polymers, we aim to compare both RDRP techniques by preparing 2-acetoxyethyl methacrylate (AcEMA) and 3-(triethoxysilyl)propyl methacrylate (TESPMA) based homopolymers. For this purpose, AcEMA and TESPMA were polymerized in 1,4-dioxane at 60 °C mediated by CuBr/N,N,N',N'-pentamethyldiethylenetriamine (PMDETA) and 2-(2-carboxylethylsulfanylthiocarbonyl-sufanyl) propionic acid (TTC) as well as cumyl dithiobenzoate (CDB) to evaluate the suitability and reliability of ATRP and RAFT to prepare such hybrid (co)polymers.zeige mehrzeige weniger
