J a p a n ## Synopsis Poly-S-carboxyniethyl-~cysteine has been prepared by debeiizylation of poly-Srarbobenzoxymethyl-bcysteine with hydrogen bromide in acetic acid. By the infrared spectroscopic method the polymer is found to be in the extended p-conformation with a n antiparallel arrangement of
## Abstract pH titration measurements of poly‐ __S__‐carboxymethyl‐L‐cysteine were undertaken in the aqueous Nacl solution in relation to the β form–random coil transition. The titration curves show a marked molecular weight dependence because of the shortened chain length of materials. Comparison
