A mouldable composition comprising a homogeneous mixture of (a) at least one particulate material insoluble in water and which is substantially unreactive with water, (b) at least one water-soluble or water-dispersible organic polymeric material, and, (c) water, characterised in that the composition also comprises an additive capable of reacting with the polymeric material to insolubilise the material with respect to water, and in that components (a), (b) and (c) are present in the composition, in proportions by volume of the composition, of respectively 40 to 90%, 2 to 25%, and not more than 60%. Optionally, the additive may also be capable of effecting coupling between the organic polymeric material and the surface of the particular material, or the composition may comprise a separate component capable of effecting said coupling. Also, a shaped product produced from the composition. |
