Well-Defined Graft Copolymers Issued from Cyclobutenyl Macromonomers by Combination of ATRP and ROMP

Synthesis and characterization of graft copolymers PnBA-g-PS by miniemulsion polymerization

“…[1][2][3][4][5][6] Especially, can be tuned by molecular design, graft copolymers have potential applications as compatibilizers, thermoplastic elastomers, impactresistant plastics, adhesive and renewable materials. Aided by broad evolution of living/controlled polymerization such as anionic polymerization, ring-opening polymerization (ROP), atom transfer radical polymerization (ATRP), single electron transfer radical polymerization (SET-LRP), nitroxide-mediated polymerization (NMP), reversible addition-fragmentation transfer (RAFT), ring-opening metathesis polymerization (ROMP), there are many opportunities in the synthesis of well-defined graft polymers with flexibility, diversity and functionality.…”

An All‐ROMP Route to Graft Copolymers

“…[2] A subsequent second polymerization joins these end-groups to form a graft copolymer. The grafts in this approach are typically prepared via carb-anionic, [3][4][5][6][7][8] oxy-anionic, [9][10][11][12] atom transfer radical polymerization (ATRP) [13][14][15] or ring opening polymerization. [16] The ring-opening metathesis polymerization (ROMP) has often Communication A new versatile synthesis strategy for macromonomers has been developed that uses the living ring-opening metathesis polymerization (ROMP) with commercial Grubbs first generation ruthenium initiators.…”

“…Early transition metal initiators based on molybdenum [3][4][5][6]8,[11][12][13][14] or tungsten [5] as well as late transition metal initiators [7,9,10,15,16] have been used for the polymerization of macromonomers.…”

Mechanism and Kinetics

“…A " grafting from " process where the controlled radical polymerization agent (brominated functional group, nitroxide, or RAFT agent) is incorporated on the polymer backbone has frequently been employed to produce grafted polymers [67] . Reduction of the termination rate due to the " living " process can result in much higher grafting yields on surfaces [68] .…”
