摘要
A process is disclosed for waterproofing materials having a fibrous structure, such as leather, persian leather or leather replacement materials, by using waterproofing agents containing sulfosuccinic acid esters. Also disclosed are waterproofing agents used to carry out this process. The sulfosuccinic acid esters are prepared by reacting maleic anhydride with monohydric or polyhydric alcohols, then by sulfitizing them. Reactive siloxanes may also be used as polyhydric alcohols.
