    摘要： The invention relates to a neutral nonionic latex comprising:(a) about 5 to about 70 weight percent of a nonionic polymer comprising polymerized free-radically polymerizable nonionic monomer, based upon the total weight of the neutral nonionic latex, wherein the free radically polymerizable nonionic monomer comprises:(i) about 90 to about 99 percent by weight of nonionic alkyl acrylate monomer; and(ii) about 1 to about 10 percent by weight of nonionic amide monomer; wherein the weight percentages of (i) and (ii) are based upon the total weight of (i) plus (ii);(b) about 30 to about 95 weight percent of an aqueous phase, based upon the total weight of the neutral nonionic latex; and(c) about 2 to about 10 weight percent of a nonionic emulsifier based upon the total weight of the nonionic polymer plus the nonionic emulsifier;wherein particles of the nonionic polymer are stabilized by the nonionic emulsifier and dispersed within the aqueous phase. The invention also relates to the neutral nonionic adhesive prepared from the latex and to adhesive coated sheet materials.

    摘要： Methods of contacting a subterranean formation are described which provide improved control or reduction of particulate migration, transport or flowback in wellbores and reservoirs, and which may do so without sacrificing substantial hydraulic conductivity. One method comprises injecting into a well-bore intersecting the subterranean formation a fluid composition comprising a first component and a second component dispersed in a carrier fluid, at least a portion of the first component or second component being provided as at least one multicomponent article having an aspect ratio greater than 1:1.1; forming a network comprising the first component; and binding the network with the second component.
