    Abstract: The invention provides a crosslinked polymer, a hydrogel, a water-based fracturing fluid comprising the same, and methods of making and using thereof. The crosslinked polymer of the invention is represented by formula (I), wherein * denotes a combining site with a polymer starting material and *? denotes an optional combining site with the polymer starting material, wherein the combining sites denoted by * and *? may be located in the same polymer molecule, or in different polymer molecules, but there are at least two combining sites located in different polymer molecules; X1 and X2, which may be the same or different, are independently an oxy (—O—) or imino (—NH—) group; X3 is an oxy (—O—) or imino (—NH—) group when *? denotes a combining site with the polymer starting material, or X3 is a halogen, NH2 or OH when *? isn't a combining site with the polymer starting material.

  • Publication number: 20180273650
    Abstract: Studies have been made for the purpose of achieving both the improvement in the storage stability of a solution-polymerized diene rubber that is modified with an alkoxysilane compound and the improvement in the physical properties of the diene rubber when blended with silica. Thus, a production method whereby it becomes possible to produce a modified solution-polymerized diene rubber having good storage stability and high reactivity with silica is developed, by introducing several tens percent of a three blanched or four blanched component that has been coupled with a tin compound into a modified solution-polymerized diene rubber, then coagulating the resultant alkoxysilane modified diene rubber with steam and then drying the coagulated product.

  • Publication number: 20180273652
    Abstract: An iminodiacetic acid type chelate resin which can be easily and efficiently produced and which can efficiently adsorb and separate metal ions; and a method for producing the same are developed. The use of a chelate rein having a carboxymethyl group introduced into primary amino groups of the polyvinylamine crosslinked polymer particles can facilitate the efficient adsorption and separation of metal ions in water. The chelate resin can be obtained by a production method in which an N-vinyl carboxylic acid amide is suspension polymerized with a crosslinkable monomer in salt water in the presence of a dispersant thereby to obtain a polyvinyl carboxylic acid amide crosslinked polymer particles, and the obtained polyvinyl carboxylic acid amide crosslinked polymer is hydrolyzed to thereby introduce a carboxymethyl group into primary amino groups of the polyvinylamine crosslinked polymer particles.
