## Abstract The synthesis of poly(ε‐L‐lysine) is described. This is a poly(ε‐amino acid) in which the ε‐amino group of lysine is condensed with the α‐carboxyl group to produce a chain backbone that is a variant of the usual one seen in proteins and the side chain is the α‐amino group.

In this paper two points are considered: the methods of evaluating the helical content 8 and the calculation of the parameters of the transition from experimental data and its interpretation. The parameter AH obtained is in good agreement with the calorimetric one and v is found to be independent of

## Abstract The heal of solution of Poly‐ε‐carbobenzoxy‐L‐lysine and of a series of its copolymers with phenylalanine was measured as a function of solvent composition. The enthalpy change of the helix‐to‐coil transition was estimated for the various cases. The previous findings that side chains do
