Abstract

The solid‐state thermomechanical behavior of polyglycine, poly‐L‐alanine, poly‐L‐valine, and poly‐L‐leucine was investigated throughout the temperature range −180° to 500°C in dry and moist nitrogen atmospheres at about 1 cps using torsional braid analysis. Transitions of the dry polymers and complexities introduced by the presence of water were investigated by temperature cycling.
