摘要： A resin composition is produced by a method including a step of rapidly freezing a latex containing fine polymer particles (A), a step of thawing the latex which has been frozen in the preceding step, a step of mixing, into the latex which has been subjected to the preceding step, a resin (B) having a specific viscosity, and after the preceding steps, a step of separating the latex into a resin composition and a water component. The resin composition is an agglutinate containing the fine polymer particles (A) and the resin (B).

摘要： The present invention is directed to additive manufacturing compositions and methods for producing additive manufacturing composite blends with oxidized discrete carbon nanotubes with dispersion agents bonded to at least one sidewall of the oxidized discrete carbon nanotubes. Such compositions are especially useful when radiation cured, sintered or melt fused.

摘要： The present invention relates to a method for preparing a nitrile-based rubber, by which the nitrile-based rubber is prepared by polymerizing a monomer mixture comprising an α,β-unsaturated nitrile-based monomer and a conjugated diene-based monomer, in the presence of an initiator and an emulsifier comprising a C30 to C60 compound having two or more carboxyl groups, a nitrile-based rubber prepared thereby, and a nitrile-based rubber composition comprising the nitrile-based rubber.

摘要： Provided herein are organic solvent-based processes for the removal of rubber from non-Hevea plants such as TKS. By the use of the processes, solid purified rubber can be obtained that contains 0.05-0.5 weight % dirt, 0.2-1.5 weight % ash, and 0.1-4 weight % resin (when it has been dried so as to contain 0.8 weight % volatile matter).

摘要： A first tire member manufacturing method includes an operation in which master batch is made, and an operation in which the master batch and high-cis polybutadiene rubber are mixed. The operation in which the master batch is made includes an operation in which carbon-black-containing pre-coagulation rubber latex is coagulated to obtain a coagulum, an operation in which a compound according to Formula (I) is added to the water-containing coagulum, and an operation in which the compound according to Formula (I) is dispersed within the coagulum. In Formula (I), R1 and R2 each indicates a hydrogen atom, an alkyl group having 1 to 20 carbons, an alkenyl group having 1 to 20 carbons, or an alkynyl group having 1 to 20 carbons. R1 and R2 may be the same or different, M+ indicates sodium ion, potassium ion, or lithium ion.

摘要： Processes for recovering natural rubber from an aqueous natural rubber latex that contains extractables and one or more additives and that is essentially free of lignocellulosic plant material are described. Natural rubber in the latex is separated from the water. Preferably, the amount of non-rubber extractables in the natural rubber is reduced by one or more extraction steps yielding a dried natural rubber.

摘要： The invention relates to a process for the preparation of a masterbatch in the liquid phase based on one or more diene elastomers and on one or more fillers which do not coagulate spontaneously with the said latex, comprising the following successive stages: preparation of a stable and homogeneous aqueous dispersion (C) by mixing one or more diene elastomer latexes (A) with one or more stable aqueous dispersions (B) of one or more fillers which do not coagulate spontaneously with the said latex and which are partially hydrophobized, homogenization of the aqueous dispersion (C), coagulation within the aqueous dispersion (C) of the diene elastomer latex with the fillers which do not coagulate spontaneously with the said latex by supplying mechanical energy, recovery of the coagulum, then drying the recovered coagulum in order to obtain the masterbatch.
