摘要： Methods for forming latexes are provided. In an embodiment, such a method comprises adding a monomer emulsion comprising water, a monomer, an acidic monomer, a hydrophilic monomer, a difunctional monomer, a first reactive surfactant, and a chain transfer agent, to a reactive surfactant solution comprising water, a second reactive surfactant, and an initiator, at a feed rate over a period of time so that monomers of the monomer emulsion undergo polymerization reactions to form resin particles in a latex. The reactive surfactant solution does not comprise monomers other than the second reactive surfactant, the reactive surfactant solution does not comprise a resin seed, and the monomer emulsion does not comprise the resin seed. The latex is characterized by a viscosity in a range of from about 10 cP to about 100 cP as measured at a solid content of about 30% and at room temperature. The latexes are also provided.

摘要： A preparation method of a molecularly imprinted polymer (MIP) for separation and concentration of 4-methylsterane compounds is provided. A template molecule, a functional monomer, a porogen, an initiator and a cross-linking agent are mixed and subjected to polymerization to prepare a polymer with the template molecule, which is then treated to remove the template molecule, so as to give the desired MIP. The template molecule is β-sitosterol or deoxycholic acid. The obtained molecularly imprinted polymer has multiple stable hole structures and binding sites inside, and has memory and recognition functions for the 4-methylsterane compounds, exhibiting excellent specific adsorption performance. The MIP can contribute to the accurate identification of correlation between depositional environment and maturity of crude oils or source rocks. A molecularly imprinted polymer prepared by such method, a chromatographic column and an application thereof are also provided.

摘要： A composition includes one or more copolymers of one or more vinylidene aromatic monomers and one or more unsaturated compounds containing nucleophilic groups, and the copolymer has on average about 0.01 to about 15.0 percent by weight of nucleophilic groups pendant from the copolymer. The copolymer is chain extended and/or branched by one or more copolymers of one or more vinylidene aromatic monomers and one or more unsaturated compounds having electrophilic groups, or a portion of the chains of the copolymer of one or more vinylidene aromatic monomers and one or more nucleophilic groups are crosslinked with other chains of the copolymer of one or more vinylidene aromatic monomers and one or more nucleophilic groups by ionic bonding of anions formed from the pendant nucleophilic groups with a metal cation having a valence of 2 or greater or complexation between pendant acid groups and metal oxides.

摘要： Electro-responsive hydrogel particles are flowed into a first wellbore formed in a subterranean formation. An electric circuit is established between the first wellbore and a second wellbore formed in the subterranean formation. An electric current is applied through the electric circuit, thereby exposing the electro-responsive hydrogel particles to an electric field and causing at least one of swelling or aggregation of the electro-responsive hydrogel particles to form a flow-diverting plug within the subterranean formation. Water is flowed into the first wellbore to increase hydrocarbon production from the second wellbore.
