微波照耀被采用帮助合成(amino-quinone )(PAQ ) poly 从在固体的 p-benzoquinone 和肼说。力量,时间,和模式的效果(连续地或间歇地) 微波,产量和 PAQ 的内在的粘性上的照耀被学习。在高力量的连续微波照耀以后在聚合导致产量和突然的暂停的快速的增加,这被显示出,由于在高反应温度的不稳定的反应物的随后的损失。或者,高力量的微波照耀对如果间歇地使用了,提起收益适用。相反,低力量的微波照耀赞成连续暴露的方法为聚合保证足够的热。在高、低的力量的两个盒子中,收益和内在的粘性能被延长暴露时间进一步支持。它与 5 min 间隔,收益和 PAQ 的内在的粘性从 p-benzoquinone 和 p 苯撑肼跟随的 5 min 照耀的六个序列在 490 W 在断断续续的照耀的一个 preliminarily 优化的条件下面被发现那能分别地象 83% 和 41.9 mL/g 一样高到达。
Microwave irradiation was employed to assist the synthesis of poly(amino-quinone) (PAQ) from p-benzoquinone and diamines in solid state. The effects of power, time, and pattern (continuously or intermittently) of microwave irradiation on yield and intrinsic viscosity of PAQs were studied. It is shown that the continuous microwave irradiation at a high power leads to rapid increase of yield and a sudden halt in polymerization afterwards, due to the subsequent loss of volatile reactants at a high reaction temperature. Alternatively, the high-power microwave irradiation is applicable to raising the yield if used intermittently. In contras4 the low-power microwave irradiation favours the way of continuous exposure to ensure sufficient heat for polymerization. In both cases of high and low power, the yield and intrinsic viscosity can be further promoted by prolonging the exposure time. It is found that under a preliminarily optimized condition of intermittent irradiation at 490 W with six sequences of 5 min irradiation followed by 5 rain interval, the yield and intrinsic viscosity of PAQ from p-benzoquinone and p-phenylene diamine can reach as high as 83% and 41.9 mL/g, respectively.
