Synthesis and applicationJunhua ZhangnullDefinitionMacro + monomerMolecular weight: 1000-10000nullHomopolymerization to comb polymerCopolymerization to graft polymernullThe first reported macromonomernullSynthetic methods for macromonomersnullLiving polymerization:
Ionic polymerization
Cationic polymerization
Controllable radical polymerization
Conventional free radical polymerizationnullnullIt’s somewhat difficult for Macromonomers’ homopolymerization
► low molar concentration
► diffusion-controlled termination Kt is lower
► self-aggregation or self-organizationnullnullAmphiphilic macromonomerIn water, polymerization rate is almost 100 times than in benzene
nullCopolymerize with A and B
Here A is conventional monomer
And B is macromonomerPoly(A-g-B)Reactivity of B is determined largely by end groups, in most cases, macromonomers’ reactivity reduce by their nature of polymer chain.nullPolymer architecture designed by macromonomersnullnullmultiinitiatornullnullnullnullnullnullX.
