Novel rheology regulators of the type of ground natural calcium carbonates, optionally being treated with a fatty acid or a salt thereof as well as their use in polymeric compositions |
摘要 |
<p>The invention relates to the selection of a natural calcium carbonate crushed to a high degree of fineness, possibly treated with one or more fatty acids or one or more of their salts or mixtures thereof, and its use as a rheology regulator for polymeric compositions. The specific surface area is 14 to 30 m<SUP>2</SUP>/g measured according to the BET method to ISO 4652, and the oil absorption is greater than 16 measured according to ISO 787-V (Rub-out method). The conditions of mixing of the constituents and manufacture are improved, as well as the properties of the final product.</p> |
