| abstract |
The present invention relates to new polymerizable compositions, based on at least one ester, soluble or dispersible in water, of a carboxylic acid alkoxyalkyl unsaturated. More specifically, these compositions contain: at least one methacrylate or an acrylate of polyalkoxy methoxy ethyl, at least one selected initiator among the alkali metal persulfates, persulfate ammonium and hydrogen peroxide, at least one polymerization accelerator, and water. These compositions can in particular be used to carry out the tightness of underground environments. |
