## Abstract Low shear viscosities have been determined for a 1 mg/ml poly(L‐lysine) solution as a function of added salt concentration in the region of the previously reported ordinary–extraordinary phase transition. The measured viscosities indicate that the polyions are far from completely extend
Water-insoluble films of poly-L-lysine, crosslinked with formaldehyde, were suspended in aqueous media and their relative lengths measured as a function of pH. A sharp transition of the polymer was observed in the pH range which corresponded with that observed in polylysine solutions by optical rota
## Abstract Clipped autocorrelation functions for the fluctuating intensity of light scattered from dilute solutions of poly‐L‐lysine in 0.2 __M__ NaBr have been observed over a wide range of time scales down to 1.83 μsec, and over a wide range of pH. Two poly‐L‐lysine samples of molecular weight 3
