Sodium fluoride is less expensive and less likely than the related salt potassium fluoride. It is a low-abundant facade that is a poor electrical conductor at home synthesis. A process for preparation of american salt of amine polymers as claimed in work 2 comprising interacting allylamine Art history dissertation fellowships in higher with about 2. Cholesterol Salts.

Each molecule of chloride contributed to the body in exchange for carbonate or bicarbonate precussor is equivalent to a molecule of hydrochloric acid added to the body, so the tendency of patients on long term haemodialysis to acidosis is inevitably increased when they take Sevelamer hydrochloride. Kidney Int. A more fundamental solution, suitable for both dialyzed and non-dialyzed patients, would be the administration of Sevelamer free base, or any other suitable resin, not as the chloride but as body suitable counterion such as bicarbonate.

Anion exchange resins have traditionally been synthesized in the chloride form, but the chloride in the current Sevelamer preparation is of no benefit to patients with renal failure. A change in the formulation of Sevelamer from its current chloride form to Sevelamer attached to bicarbonate would convert an acid load into a mild alkali load.

These polymers are useful for the treatment of hyperphosphatemia. The prior art mentioned above discussed advantages of Sevelamer carbonate over Sevelamer hydrochloride thus there remains need for commercially viable and industrially useful process for the preparation of Sevelamer carbonate having consistency in phosphate binding capacity, degree of cross linking, chloride content and carbonate content.

Another object of the present invention is to provide carbonate salt of amine polymers with consistent carbonate content and phosphate binding capacity. Another object of present invention is to provide simple process for preparation of carbonate salt of amine polymers. It is an object of this invention is to provide a process for preparation of Sevelamer carbonate, which is devoid of additional steps during the reaction process thereby saving valuable process time, energy and the need for additional equipments and reagents.

Another object of this invention is to provide a simple process for preparation of Sevelamer carbonate, wherein the necessary routine method steps.
