Abstract: In this paper, by using the generating function method, the expressions of the average molecular weight and the molecular weight distributions of ternary multi- block copolymers of type are derived, giving a theoretical method for characterizating the molecular structure of this block copolymer.The properties of some block copolymers composed of the prepoly-mers with a special molecular weight distribution are discussed.

Key words: Multi- block copolymer, Generating function, Average molecular weight, Molecular weight distribution
