Linker chemistry is a kind of effective approach for polymer synthesis

which possesses high activity

high yield

high selectivity

and is sensitive to the specifically groups

fits for the link or ligation of the polymers and connect with molecules.This review introduces and summarizes our progress on synthesis of functional polymers with well-defined structure via linker chemistry.The linkages include condensation reaction

ring-opening reaction

click chemistry

and reversible linkages. Finally

a proper prospect of the development of linker chemistry has been discussed.
