An object of the present invention is to provide a multicomponent copolymer for use for producing a rubber composition and a rubber product having high abrasion resistance and wet performance. Further, the invention is to provide a rubber composition containing the multicomponent copolymer, a crosslinked rubber composition produced by crosslinking the rubber composition, and a tire and a rubber product using the rubber composition or the crosslinked rubber composition. The multicomponent copolymer of the invention contains a conjugated diene unit, a non-conjugated olefin unit and an aromatic vinyl unit, wherein the content of the aromatic vinyl unit is 5 mol% or more and less than 50 mol% of the whole multicomponent copolymer and the content of the non-conjugated olefin unit is more than 0 mol% and 50 mol% or less of the whole multicomponent copolymer.

There is provided a resin-treated pigment that is useful as a coloring agent for color filters or inkjet inks, that can expand a hue range and improve performances such as color density, color developability, and transparency, and that is excellent in properties such as dispersibility and dispersion stability of pigments, re-dissolvability, and alkali-solubility. An A-B block copolymer 90% by mass or more of which is constituted by a methacrylate-based monomer or methacrylate-based monomers, in which the block A has a carboxy group-containing methacrylate as a constituent, and the block B has an ionic bond moiety represented by formula (1) as a constitutional unit, the ionic bond moiety containing a methacrylate, and an organic coloring matter having one or more sulfonate ions each being bonded thereto and each being a counter ion of a nitrogen cation of a quaternary ammonium salt.
摘要:
Sorbent polymeric material suitable for capturing formaldehyde, polymeric material resulting from the capture of formaldehyde by the sorbent polymeric material, and methods for capturing formaldehyde are provided. The sorbent polymeric material has multiple aromatic rings and can be formed by initially preparing a precursor polymeric material from a polymerizable composition that contains a free-radically polymerizable spirobisindane monomer. The precursor polymeric material is subsequently treated with a sulfonyl-containing compound to form groups of formula —SO2R5 where each R5 is independently —NH2 or —NR6-Q-NR6R7. Each R6 is hydrogen or an alkyl. Each R7 is hydrogen or —C(═NH)—NH2. Each Q is a single bond, alkylene, or a group of formula -(Q1-NR6)x-Q2- where each Q1 is an alkylene, each Q2 is an alkylene, and x is in an integer in a range of 1 to 4.

摘要:
A styrene based water soluble polymer containing pendant sulfonated calix[4]arene groups has been synthesized by using free radical polymerization combined with post-polymerization sulfonation chemistry. The monomer 25-(4-vinylbenzyl)-26, 27, 28-hydroxy-calix[4]arene was prepared in 3 steps: (1) reduction of 4-vinyl benzoic acid to the respective alcohol (2) formation of the bromide by the Appel reaction and (3) synthesis of the respective ether by Williamson O-alkylation reaction with calix[4]arene. Polymerization was accomplished by azobisisobutyronitrile (AIBN) initiated free radical polymerization technique. Electro-responsive properties of the sulfonated polymer were studied wherein a response to electrochemical stimulus is observed when guest molecules of methyl viologen are incorporated with polymerized 25-(4-vinylbenzyl)-26, 27, 28-hydroxy-calix[4]arene.

Described herein are modified sulfonated block copolymers which comprise at least two polymer end blocks A and at least one polymer interior block B, wherein each A block contains essentially no sulfonic acid or sulfonate functional groups and each B block comprises sulfonation susceptible monomer units and, based on the number of the sulfonation susceptible monomer units, from about 10 to about 100 mol % of a functional group of formula (I) —SO2—NR1R2 (I) or of a salt thereof, methods of making them as well as methods of using them, e.g., as membrane materials for electrically or osmotically driven applications.
摘要:
Sulfonyl-containing polymeric materials are prepared by treating a precursor polymeric material with a sulfonyl-containing compound. The precursor polymeric materials are formed from a polymerizable composition that contains a crosslinker that is a free-radically polymerizable spirobisindane monomer. The sulfonyl-containing polymeric material can be used as an ion exchange resin.
