Abstract
Water soluble polymerizable acrylic prepolymers can be formed from ethylenically unsaturated monomers that include monomers that provide a pendant group that is a blocked, saturated, ethylenic group, followed by unblocking the pendant saturated ethylenic group to leave a pendant ethylenically unsaturated group. These prepolymers can be copolymerized through these unsaturated groups, for instance after impregnation into a permeable substrate as in chemical grouting or shut off processes, to form cross linked solid polymers. The polymerizable monomers that are ethylenically unsaturated but which also include the blocked ethylenic group are also novel.
