Abstract

The stabilizing effect of various synthetic polymers as well as naturally occurring urinary mucoproteins and mucopolysaccharides upon the kinetics of the calcium oxalate system has been tested and evaluated by calculating slopes (rates) and lags (nucleation time) of calcium oxalate formation. This was accomplished by means of a Fisher Nefluorophorometer. The experimental part was carried out in aqueous as well as urinary media. This problem has been also approached by testing the calcium‐bonding properties of the polymers and urinary fractions. The results of the conducted experiments show that nondialyzable urinary fractions and polymers of glucose and its sulfonated derivatives, and to a lesser extent polymers of mannuronic acid exhibit some diminishing effect upon the rate of calcium oxalate formation, while prolonging their nucleation times.

Phase transformation of calcium oxalate dihydrate (COD) into the thermodynamically stable monohydrate (COM) in anionic (sodium dodecyl sulfate (SDS)) and cationic (dodecylammonium chloride) surfactant solutions has been studied. Both surfactants inhibit, but do not stop transformation from COD to CO

## Abstract **Summary:** This paper describes the behavior of some polysaccharides with well‐known chemical structures and in which the influence of cooperative secondary interactions play an important role. The roles played by hydrophobic and ionic interactions (including ionic selectivity) on pol
