Poly(acrylic acid) and its salts have been known to have useful binding properties for some thirty years they have been used for soil consolidation (Lambe Michaels, 1954 Hopkins, 1955 Wilson Crisp, 1977) and as a flocculant (Woodberry, 1961). The most interesting of these applications is the in situ polymerization of calcium acrylate added to soil (de Mello, Hauser Lambe, 1953). But here we are concerned with cements formed from these polyacids. [Pg.90]

Acrylates are not new as soil treatment agents. As early as the mid 1950s, calcium acrylate was researched by the United States Army Corps of Engineers [20], and detailed data on acrylate was available in chemical publications [21]. [Pg.217]

Tabtiang and Venables [20] studied the reaction of acrylic acid with the surface of calcium carbonate. The coating was carried out by means of a dry method and their results again demonstrate the complexities that can be encountered. IR spectro-metric analysis of the coated fillers showed that all the acid was converted to the salt form, even when amounts well in excess of that required for a monolayer were used. However, the authors found no evidence of monolayer adsorption, with about half the added material becoming insoluble in xylene, a good solvent for calcium acrylate, at all levels of addition. They concluded that, with the method of coating employed, small droplets react with the filler to produce calcium acrylate, some of which is bound to the filler, or insolubilized in some way, while the rest remains as the free salt. [Pg.127]

Calcium acrylate dissolves readily in water to give a reasonably stable solution at room temperature. At 24°C, 44 gm of calcium acrylate will dissolve in 100 gm of water. The freezing point of such a solution is approximately -12°C [109]. [Pg.342]

As expected, the polymeric calcium acrylate may act as an ion-exchange resin. If monovalent cations are exchanged for calcium ions, the ionic cross-linkages are destroyed and water-soluble polymers such as poly(sodium acrylate) may form. Clearly this would interfere with proper soil stabilization [109]. [Pg.343]

The polymerization of calcium acrylate may be initiated with typical redox systems such as ammonium persulfate-sodium thiosulfate and certain peroxides with reducing agents such as sodium thiosulfate. Hydroxylamine hydrochloride, hydrazine hydrate, and tetramethylenepentamine are also suitable reducing agents with certain oxidizing agents [110]. [Pg.343]

In the presence of a sandy soil, 5% of Initiator based on the quantity of calcium acrylate in the soil will cause gelation in about 80 min 20-25% of initiator causes gel formation in 6-8 min and 50% of initiator affords a gel time of about 1 min. [Pg.343]

The quantity of water present in the soil influences results. Water levels of up to 25% of the soil weight have been treated satisfactorily with 10% of calcium acrylate. [Pg.343]

Hydrogen- and deuterium-atom bombardment have been used to initiate the polymerization of barium methacrylate dihydrate. The process is said to be initiated by the diffusion of hydrogen atoms in solid-state barium methacrylate dihydrate. By this method, large amounts of polymer form very rapidly, unlike in polymerizations initiated by y-radiation [112]. y-Radiation has been used in the solid-state polymerization of potassium acrylate, calcium acrylate, barium acrylate, and uranyl acrylate [113]. [Pg.344]

Aqueous solutions of Cu ", Co " and acrylates are medium-strength electrolytes a plot of the molar electrical conductivity vj. concentration is described satisfactorily by the Kolrausch equation. For 0.05 M aqueous solutions of calcium acrylate (Acr) and methacrylate at 25°C, the specific electrical conductivities, AT, are 5.16 x 10 5 and 2.787 X 10 Ohm mol and the degrees of dissociation, a, are 0.46 and 0.2, respectively. The degrees of dissociation of Zn, Pb, and Ba acrylates (M(Acr)2) in methanol are sufficient for the M(Acr)+ cations that are formed to react with radical initiators (e.g., alkylcobalt chelates with tridentate Schilf bases) to give alkyl free radicals, which induce radical polymeri2ation of MCM even at low temperatures (5-10°C). For other types of MCM ( v-, n-types, see above), metal elimination processes are less typical and in some cases (i.e., chelate type), these processes do not occur at all. [Pg.176]
