摘要： The present invention relates to a styrene-based resin having a weight average molecular weight Mw′ as determined by the GPC-MALS method of 1,000,000 or more and 5,000,000 or less, a degree of long-chain branching of 0.2 or more per 1,000 styrene units, and a tetrahydrofuran-insoluble matter of 0.1% by weight or less (including 0), the styrene-based resin being free from a component derived from a polyfunctional monomer in a molecular chain thereof. In a method for producing this styrene-based resin, in an impregnation step of adding a polymerization initiator and a styrene monomer in an aqueous medium, thereby impregnating the polymerization initiator and the styrene monomer in the seed particle at a temperature at which polymerization of the styrene monomer does not substantially proceed, the amount of the styrene monomer is 20 to 200 parts by weight based on 100 parts by weight of the seed particle; and in an additional impregnation polymerization step of graft polymerizing the styrene monomer on the styrene-based resin, the addition amount of the styrene monomer is 50 to 700 parts by weight based on 100 parts by weight of the seed particle, and the content of the styrene monomer in the seed particle is held at 10% by weight or less.

摘要： A system for continuously treating recycled polystyrene material includes a hopper/densifier configured to feed recycled polystyrene material into the system. An extruder can turn the recycled polystyrene material into a molten material. In some embodiments, the extruder uses thermal fluids, electric heaters, and/or a separate heater. Solvents, such as toluene, xylenes, cymenes, and/or terpinenes can aid in generating the molten material. The molten material can be depolymerized in a reactor and a catalyst can be used to aid the depolymerizing. In certain embodiments, the catalyst is contained in a permeable container. In some embodiments, copolymers/monomers are grafted onto the depolymerized material. The depolymerized molten material can be cooled via a heat exchanger. The product can be isolated by extraction, distillation, and/or separation. In some embodiments, the product is treated through filtration and absorption media. In some embodiments, multiple reactors are used.

摘要： Provided is a solid phase carrier which has high water dispersibility, allows facilitated binding of a ligand to a reactive functional group, and exhibits suppressed non-specific adsorption, and with which, in the case of using the solid phase carrier by having a ligand bound thereto, for example, detection of a target substance can be carried out with high sensitivity and low noise. Disclosed is a solid phase carrier having bound thereto a polymer including a structural unit represented by the following Formula (1) and a structural unit represented by the following Formula (2): wherein in Formula (1), R1 represents a hydrogen atom or a methyl group; and
R2 represents an organic group having a zwitterionic structure, in Formula (2),
R3 represents a hydrogen atom or a methyl group
R4 represents —(C═O)—O—*, —(C═O)—NR6—* (wherein R6 represents a hydrogen atom or a methyl group; and the symbol * represents a position of bonding to R5 in Formula (2)), or a phenylene group;
in a case in which R4 represents —(C═O)—O—*, R5 represents a hydrogen atom, or an organic group having a reactive functional group, and in a case in which R4 represents —(C═O)—NR6—* or a phenylene group, R5 represents an organic group having a reactive functional group,

摘要： Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that benefit from the unexpected properties of the silane-functionalized resins. Silane-functionalized resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the silane-functionalized resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, and wet braking performance.
