ABSTRACT:
Polymer compounds resulting from the condensation of polyacrylic acids having a molecular weight comprised between 10,000 and 2,000,000 and alkylamines containing at least 12 carbon atoms in their chain. These products constitute paraffin deposit inhibitors and pour point depressants for crude petroleum oils.
