Abstract
Abstract A process of stabilizing soil which comprises contacting such soil with an aqueous solution of a water-soluble diacrylate ester of a polyoxyalkylene glycol monomer, which solution also contains a water-soluble polymerization catalyst capable of polymerizing the monomer into a water-insoluble gel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
73 words
A process of stabilizing soil which comprises contacting from about 3 to about 20 parts by weight of such soil with about one part by weight of an aqueous solution containing at least 0.5 weight percent of a water-soluble diacrylate ester of a polyoxyalkylene glycol monomer having a molecular weight of at least 300, which solution also contains a water-soluble free radical polymerization catalyst capable of polymerizing the monomer into a water-insoluble gel.
Claim 2
Dependent Claim
73 words
A process of stabilizing soil which comprises contacting from about 3 to about 20 parts by weight of such soil with about one part by weight of an aqueous solution containing at least 0.5 weight percent of a water-soluble diacrylate ester of a polyoxyalkylene glycol monomer having a molecular weight of at least 300, which solution also contains a water-soluble free radical polymerization catalyst capable of polymerizing the monomer into a water-insoluble gel.
Claim 3
Dependent Claim
35 words
The process of claim 1 where the aqueous solution also contains from between 2 and 50% by weight of a water-soluble vinyl monomer capable of copolymerizing with the water-soluble diacrylate ester of a polyoxyalkylene glycol.
