Abstract
The selected physicochemical properties of water-thinnable poly(acrylic acid)/sodium salt of carboxymethyl starch (PAA/CMS-Na) compositions - new environmentally friendly polymer binding agents - were investigated as a function of time. The aqueous composition PAA/CMS-Na was stored in closed vessels in a cooling chamber at 10 degrees C. During the three-month storage period the changes of coloration, viscosity, wetting angle on quartz glass, structure and size distribution of the binding agent particles were studied. On this basis, the stability of the binder properties was preliminarily evaluated. Additionally, the moulding sands containing an aqueous composition PAA/CMS-Na as a binder (stored for a week or three months) were prepared, hardened and subjected to the bending strength tests. It was found, that after three months of storage under conditions resembling those found in a foundry the new binder did not lose its properties as a binding agent for the moulding sand.
