微波辅助聚合物化学：Heck反应，酯交换反应，Baeyer- Villiger氧化反应，恶唑啉(oxazoline)聚合反应，丙烯酰胺以及多孔材料聚合反应摘要若干问题仍然开放论及微波辐射对有机和高分子化学的不同影响。因此, 对相关的调查实验结果进行分析，我们阐明三个微波辐射的主要影响：有效的非接触式加热，加速效果，以及我们专门称的特殊效果。在本文中，第一: 利用HECK-缩聚反应( HECK-POLYCONDENSATION) 以及通过微波辅助合成聚合物（2, 5-dibutoxy-1, 4-phenylenevinylene)作为一个例子证明微波的 “有效地加热(EFFICIENT HEATING)”。第二: 通过Baeyer–Villiger 反应合成较高内酯的1-oxa-2-oxocyclooctanone and 1-oxa-2-oxocyclononanon作为一个例子证明微波的 “加速效果(ACCELERATING EFFECT)” 。第三:我们最近的调查工作也给予更详细的微波效应的解释，并提供特殊微波效果(SPECIAL MICROWAVE EFFECT)的实例。 Microwave-assisted polymer chemistry: Heck-reaction,transesterification, Baeyer–Villiger oxidation, oxazoline polymerization, acrylamides, and porous materials Abstract—Several questions are still open concerning the different effects of microwave (MW) irradiation in organic and macromolecular chemistry. Analyzing experimental results on a relatively broad investigation area, we came to elucidate three main effects of microwave irradiation: efficient non-contact heating, an accelerating effect, and what we term a special effect. In this paper, we report the first MW assisted synthesis of poly (2, 5-dibutoxy-1, 4-phenylenevinylene) via Heck-polycondensation as an example for efficient heating. The facile synthesis of the higher lactones 1-oxa-2-oxocyclooctanone and 1-oxa-2-oxocyclononanone via Baeyer–Villiger reaction offers indeed an example for theMW-accelerating effect. A survey of our recent work is also given to explain the effects more in detail and to provide examples of the special MWeffect.
