Abstract: Generally,the theoretical treatment of configurational sequence distribution has been made by statistical method.In this paper,we solve the kinetic equations of living copolymerization in Bernoulli and Markov processes with the aid of linear differential technique and obtain the sequence distribution,the functions for number average length,weight average length and sequence fraction.On the basis of these,we propose the decision equations of Bernoulli process as follows.which are a modification of Bovey's map.If the reaction system falls under Bernoulli process,fraction of isotac-tic,syndiotactic and heterotactic configuration PI,PS,PHdoes not depend on reaction time,monomer conversion and initial concentration of monomer.Alternatively,in the case of the first Markov proces,fraction of configuration varies with time,monomer concentration and approaches a definite limit as propagation parameter x→∞ It is proved that the theoretical results are in agreement with experimental data.
