Abstract: On the basis of former studies found in literatures,the mechanism of group transfer polymerization (GTP) activated by ionic field was proposed.In this mechanism,initiator is activated by a special ionic field produced by anionic catalyst.The intensity of the field enjoyed by each molecule of imtiator(Qi) is directly proportional to total intensity of the field (Q) which is directly proportional to the equivalent concentration of catalyst,and is inversely proportional to the equivalent concentration of initiator (n),i.e.Qi=Q/n.Along as Qi reach a certain value,i.e.Qi≥Qmm,GTP will take place.Along with the raise of Qi value,activation extent of initiator increases,induction period of polymerization shortens,and the speed of polymerization increases.
