摘要： The present invention relates to a catalyst for a hydrocarbon resin hydrogenation reaction and a preparation method for the same, wherein the catalyst is a nickel powder catalyst including nickel (Ni), copper (Cu), and sulfur (S), and more particularly, a nickel-based catalyst for a hydrogenation reaction, which is added to a hydrogenation reaction in order to improve the color of the hydrocarbon resin. According to an embodiment of the present invention, provided is a catalyst for a hydrogenation reaction, includes 40-80 parts by weight of nickel, 0.01-5 parts by weight of copper, 1-10 parts by weight of sulfur, and 10-60 parts by weight of a silica support based on 100 parts by weight of the entire dried catalyst including a support. Therefore, the catalyst can improve the quality of hydrocarbon resin. Furthermore, the catalyst can provide colorless, odorless, and transparent water-white hydrocarbon resin with improved thermal stability by removing unsaturated bonds in the hydrocarbon resin.

摘要： Methods for resin hydrogenation and decoloration may comprise reacting a resin mixture with a sulfided bimetallic catalyst and excess hydrogen under conditions effective to form a hydrogenated resin mixture, the resin mixture comprising an oligomerized reaction product of at least one polymerizable monomer containing an olefinic unsaturation and a solvent; providing the hydrogenated resin mixture directly to a noble metal catalyst; and reacting the hydrogenated resin mixture in the presence of the noble metal catalyst under conditions effective to form a decolorized resin mixture. Decolorized resin compositions comprising a decolorized resin mixture formed in accordance with the foregoing may have a yellowness index of about 10 or below, as measured by ASTM E313.

摘要： A method of exchanging or transforming end groups in and/or improving the ferroelectric properties of a PVDF-TrFE co-polymer is disclosed. A bulky or chemically dissimilar end group, such as an iodine, sulfate, aldehyde or carboxylic acid end group, may be transformed to a hydrogen, fluorine or chlorine atom. A method of making a PVDF-TrFE co-polymer is disclosed, including polymerizing a mixture of VDF and TrFE using an initiator, and transforming a bulky or chemically dissimilar end group to a hydrogen, fluorine or chlorine atom. A PVDF-TrFE co-polymer or other fluorinated alkene polymer is also disclosed. The co-polymer may be used as a ferroelectric, electromechanical, piezoelectric or dielectric material in an electronic device.

摘要： Residual hydrogenation catalyst produced from reduction of nitrile rubber is recovered by a chelation step using a chelating agent and a series of extraction using semi-coagulation with polar solvents and an optional washing steps for the separation of catalyst-chelating agent complex from hydrogenated nitrile rubber solution. The chelating agent is selected from xanthate, dithiocarbamate, and trithiocarbonate compounds.
