Abstract: A functional styrene-butadiene copolymer is disclosed. More specifically, the copolymer is prepared by radical polymerization of a styrene monomer, a butadiene monomer and an epoxy acrylate monomer in an emulsion state and ring-opening of the resultant styrene-butadiene-epoxy acrylate copolymer. When blended with silica, the disclosed copolymer provides excellent wet stopping performance and superior wear resistance. Therefore, it can be usefully applied for industrial materials including fuel-efficient tires, snow tires, belts, hoses, etc.

Abstract: Disclosed is a hydrogen combustion system with closed-cycle recycling comprising a hydrogen combustion system with closed-cycle recycling of exhaust gas, comprising: a hydrogen supplier 110 which supply hydrogen used as a fuel, a combustion chamber 120 which is located in the engine 130 and connected to the hydrogen supplying pipe 111 in which the hydrogen is combusted, a condenser 140 which converts the hot exhaust gas emitted through the discharge pipe 121 installed on the outlet of the combustion chamber 120 into the cold exhaust gas and condensed water, and a recycling pipe 150 which performs recycling of a part of the cold exhaust gas from the condenser 140 to the inlet of the combustion chamber 120.

Abstract: Disclosed is an interfacial polymer for a network used as a coupling agent in mixing of rubber-silica. More particularly, the interfacial polymer for a rubber-silica network is a block copolymer containing a copolymer of conjugated diene and vinyl aromatic monomers, in which when used as a coupling agent in the mixing of synthetic rubber and silica (an inorganic material), the polymer enhances silica dispersibility within the rubber, and improves compatibility and processability, resulting in considerable improvement in the dynamic property as well as the mechanical property of the rubber, and when used in a tire, etc., it enhances automobile braking performance and reduces rolling resistance.

Abstract: Disclosed are a novel chain transfer agent having a trichloromethyl functional group bonded at an end thereof, an end-modified styrene-butadiene copolymer prepared by using the chain transfer agent, and an organic-inorganic composite obtained by mixing the end-modified styrene-butadiene copolymer with silica. The disclosed end-modified styrene-butadiene copolymer has a high affinity with silica because its end is modified with a hydrophilic chain transfer agent. Thus, the organic-inorganic composite including the mixture of the copolymer with silica is useful as a material for the manufacture of rubber products such as a tire, a sole, a rubber hose, or a rubber belt.

Abstract: Further improvements have been made in processes for controlled polymerization of free radically (co)polymerizable monomers mediated by a transition metal complex participating in a redox reaction which involves transfer of a radically transferable atom or group to and from an initiator or dormant polymer and the growing active polymer chain ends. Two improvements involve the choice of counterion in the transition metal complex. In one improvement the transition metal is held in close conjunction with a solid support through interaction with a counterion directly attached to the support. This cognition also allows for improvements in catalyst utilization including catalyst recovery and recycle. In another improvement, particularly suitable for controlled polymerization of certain monomers with an expanded range of transition metals, the function of counterion and ligand in the development of the transition metal based catalyst is superseded by use of salt containing a soluble organic counterion.
