A new tetra polymerization model was proposed to handling the atom transfer copolymerization as well as the microstructure of its products.According to this model

computer simulation has been carried on to produce this ATRcP propagation including activation-deactivation process.After filtering two “monomers" which represent the dormant state of activate units

the chains' microstructure was found to be the same as that of the stationary FRcP

and all the values of structure parameters had nothing to do with the dormancy and reactivation probabilities.This conclusion can be supported by the existing experimental results.It is concluded that under stationary conditions

the copolymer's microstructure of the ATRcP is the same as that of the FRcP product

this structure includes the average segment length

composition

triad sequence concentration and segment length distribution.
