摘要：

By considering the effect of neighbouring monomer units in depropagating polymer chain radicals on the formation of degradation products, a new boundary effect theory was developed in order to elucidate the sequence distributions in vinyl-type copolymers using the corresponding monomer yields. This theory was applied succesfully to the calculation of the sequence distributions in methyl methacrylate-styrene copolymers in terms of the run numbers. The significance of newly introduced parameters (monomer formation probability constants) is also discussed. © 1979.
