The amino‐acid‐sequence distribution in poly(γ‐benzyl‐ L ‐glutamate, L ‐methionine) prepared by polymerization of the respective N ‐carboxyanhydrides has been investigated. This copolymer was converted first to poly( L ‐glutamic acid, L ‐methionine), which was subsequently cleaved by treatment with cyanogen bromide. The resulting material was fractionated into oligomers of (glutamic acid) n ‐homoserine whose relative molar amounts were determined quantitatively. The results have been compared with those for a random incorporation of the methionine in a γ‐benzylglutamate host polymer. Fairly close agreement has been found.
