## Abstract Ultrasonic absorption measurements were carried out on solutions of polybenzyl‐L‐aspartate (PBLA) in chloroform–dichloroacetic acid (DCA) and in 1,2‐dichloroethane (DCE)–DCA, in the range 3.9–155 MHZ. The helix–coil transition of PBLA produces an increase of absorption which is larger i

The objective has been to establish if those ions which are known to change the stability of the struct,ure of proteins, have any influence on the properties of ionizable polypeptides. Potentiometric titrations and complementary optical rotation data are presented for aqueous solutions of poly-L-lys
