Business card printing and membership card making Ink viscosity in business card printing and membership card making faster, rollers and plates after the ink friction heats gets smaller, on the rising of the ambient temperature, the viscosity of ink will drift away, this time using the innovativeink, with the temperature increase, decrease viscosity is referred to as a viscosity index of added value, that is, the viscosity index is a viscosity index of temperature-dependent, for example, at a low temperature solvent oil sludge formation, if you join methylmetacrylate and transfromer monosomic of multi-fault copolymer exclude this.

制卡和会员卡制作油墨的粘度在随制卡和会员卡制作速度的加快时，因墨辊与印版摩擦后油墨温度升高而变小外，当环境温度的上升后，油墨的粘度也会逐渐变小，这种在使用油墨时，随着温度的上升，其粘度下降的行为被称为粘度指数增加值，即粘度指数是表示粘度随温度变化的指标，例如，溶剂油在低温下形成淤浆时，如果加入甲基丙烯酸酯和极性单体的共聚物排除此类故障的发生。

Then, the multidentate amine immobilized on silica gel was used as ligand for CuCl in ATRA of CCl_4 with MMA and methyl trichloroacetate with St repeatly. The conversion and purity of the product were determined through the gas chromatography and ~1H NMR respectively. Finally, the multidentate amine immobilized on silica gel was used as ligand for CuCl in ATRP of St initiated by TCPP and MMA initiated by MMTCB. The number average molecular weights of the polymers were determined through GPC.

The results indicate that the imprinted polymers synthesized by methacrylic acid as functional monomer exhibite the best regioselectivity, yielding up to 49.6% pare and 44.1% ortho isomer of nitrotoluene.

结果显示分子印迹聚合物提高了甲苯的对位选择性硝化能力，并且以甲基丙烯酸为功能单体的分子印迹聚合物的对位选择性最好，邻对比为0.89。

The possible mechanism was discussed. These bowl-shaped aggregates are promising candidates for nano reactor or drug carrier.4 2,7-dimethylene-1,4,6-trioxaspiro[4, 4]nonane with two vinyls was prepared to be used as electron-donor and crosslinker. The ATRP of this crosslinker and excess methylacrylate (used as electron-accpetor) was proved to mainly form homopolymers. With the chain-transfer agent S-1-Dodecyl-S\'-(α,α\'-dimethyl-α-acetic acid)trithiocarbonate, the copolymerization of the spiro hydrocarbon, maleic anhydride and MA by RAFT method produced star PMA.
