Effect of activation-deactivation on microstructure of the product of atom transfer radical copolymerization

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.
