摘要： The present invention provides a thiocarbonylthio compound represented by formula (I) Wherein n is an integer of 0 to 3; R1 is alkyl, haloalkyl, alkenyl, aryl, alkylaryl, haloalkylaryl, arylalkyl, aminoalkyl, alkylamino, alkoxy, alkoxyaryl, alkyl sulfide, or alkylsilyl; R2 and R3 are independently H, alkyl, haloalkyl, alkenyl, aryl, alkylaryl, arylalkyl, aminoalkyl, alkylamino, alkoxy, alkyl sulfide, or alkylsilyl; R4 and R5 are independently H, alkyl, haloalkyl, alkenyl, aryl, alkylaryl, arylalkyl, aminoalkyl, alkylamino, alkoxy, alkyl sulfide, or alkylsilyl, or R4 and R5 link together with the carbon atoms to which they are attached to form a ring system; and Y is O or S. The thiocarbonylthio compound can be used in a living free radical polymerization to obtain a polymer with high conversion and low polydispersity.
