The copolymer of caprolactam (CL) and octamethyl cyclotetrasiloxane (D4) has been obtained successfully by ring-opening copolymerization under the same anionic catalytic condition, and characterized by H-NMR and IR spectra. When the monomer ratio D4: CL was 15 wt%, the percentage of monomer D4 entered into the copolymer chain may reach 76.3-83.5. The microph-ase separation of two components was observed by SEM. At appropriate proportion of monomer reactants, the copolymerized product had lower water sorption,...

The copolymer of caprolactam (CL) and octamethyl cyclotetrasiloxane (D4) has been obtained successfully by ring-opening copolymerization under the same anionic catalytic condition, and characterized by H-NMR and IR spectra. When the monomer ratio D4: CL was 15 wt%, the percentage of monomer D4 entered into the copolymer chain may reach 76.3-83.5. The microph-ase separation of two components was observed by SEM. At appropriate proportion of monomer reactants, the copolymerized product had lower water sorption, lower coefficient of kinetic friction, and higher impact strength than that of polycaprolactam.

介绍在己内酰胺阴离子催化聚合反应中,添加六甲基磷酰三胺作增韧改性剂制备改性MC尼龙。用DSC法研究了增韧改性MC尼龙的热性能,结果表明,随着六甲基磷酰三胺组分的增加,MC尼龙的熔融温度、熔融热焓、结晶度等均降低,材料力学性能变化的趋向与热性能变化相吻合。

There exist two theories of the action of a catlyst of coal burning. the theories of Oxygentransfer and of Electron - transfer. According to these theories, the catalyst can enhance the rate of production of volatiles from coal, decrease buming temperature, increase ignition speed of coal and burning rate of coke. It also has some effects in desulphurizing and denitrogenation. With fixed amounts and the same anion, the order of activity of different cations is Cs> Rb> K > Na> Ba >Li >Sr >Ca> Mg> Be.For the same...

The ash in coal is an internal catalyst. The mode of external catalyst seriously affects catalytic effect.

煤的催化燃烧存在氧传递和电子转移两种理论解释,催化剂能够增加煤的挥发分的拆出速率,缩短燃烧时间,提高煤的着火速度,加快焦碳的燃烧速度,并具有脱硫脱氮作用。对于相同的阴离子,不同阳离子的催化活性顺序是Cs>Rb>K>Na>Ba>Li>Sr>Ca>Mg>Be,对于相同的阳离子,不同阴离子的催化活性顺序是OH->CO2-3>CL->SO2-4。灰是内存催化剂。外加催化剂的添加方法严重地影响催化效果。
