The Atom Transfer Radical Polymerization(ATRP) is a new type of controllable/active polymerization technology

which can effectively realize the structure design of the polymer molecular and precise control the polymer molecular structure. In this paper

we firstly introduce latest advances about the preparation methods of the ATRP macromolecular initiator in recent years

such as functional group reaction

coupling reaction and free radical polymerization. Then

we emphatically summarize the structure design of the the polymer through controlling the active position of macromolecules initiators briefly. Moreover

we focus on introducing the latest application of the macromolecular initiator through ATRP reaction in the structure design of the polymer

such as block polymers

comblike polymer

molecular brush polymer

dendritic polymers

branched polymer

star polymer.
