Abstract:
A method of making a water soluble polymer composition comprising blending a water soluble polymer with at least 15% by weight of the total weight of the composition of a hygroscopic salt to act as a lubricant to render the polymer extrudable and/or mouldable, wherein the water content of the composition is of less than 10% by weight of the total weight of the composition.
