“…Both ATRP and RAFT techniques enable controlled synthesis, which can even be carried out in one‐pot but sequential monomer polymerizations for construction of hierarchal structures. Both thioester (Lee et al, 2017; Willcock & O'Reilly, 2010) and halide (Anastasaki, Willenbacher, Fleischmann, Gutekunst, & Hawker, 2017) terminated polymers can undergo transformation to functionalize, or inert (Chong, Moad, Rizzardo, & Thang, 2007; Gutekunst et al, 2017) chain ends. In addition to the use of vinyl‐containing inimer and transmer in radical‐based SCVP, other feed stocks are capable of forming hyperbranched polymers by ring‐opening polymerizations using acid or base catalysts.…”
