High density polyester products, compositions and uses

The present invention relates to a polyester product having a higher atypical density at 25 DEG C of greater than 1 g/cm3, the polyester product comprising the reaction product of one or more C2-C12 polyacids and one or more polyols. The invention also relates to a process for preparing a polyester product, to compositions comprising or comprising a polyester product and to the use of such compositions. More particularly, compositions comprising the present polyesters can be advantageously used in aqueous environmental applications or other applications in which environmental containment is important consideration. 本发明涉及在25℃下具有大于1g/cm3较高的非典型密度的聚酯产品，本聚酯产品包括一种或多种C2-C12多元酸和一种或多种多元醇的反应产物。本发明还涉及制备聚酯产品的方法、包含或包括聚酯产品的组合物和此类组合物的用途。更特别地，包含本聚酯的组合物可有利地用于水性环境应用或其中环境遏制是重要考虑的其它应用。
