“…has applied these principles to the step copolymerization of the system AA, BB, CC where BB does not react with CC; in such a system six types of polymeric chains exist classified with respect to their end groups: A",A, B",B, C",C, A",B, A",C, B",C. Each has a distribution of chain lengths (6) which can be obtained by the reasoning which leads to equation (3). has applied these principles to the step copolymerization of the system AA, BB, CC where BB does not react with CC; in such a system six types of polymeric chains exist classified with respect to their end groups: A",A, B",B, C",C, A",B, A",C, B",C.
