紫外光谱证实了高分子的结构对二苯甲酮单元的最大紫外吸收几乎没有影响。
苯骈三唑、邻羟基二苯甲酮、水杨酸酯类化合物构成了几种重要类型的紫外吸收剂。
光聚合引发剂如二苯甲酮在紫外线照射下,成为带不配对电子的自由基团(图1)。
就改善木塑复合材料老化后的表面色变和弯曲性能损失而言,苯并三唑类比二苯甲酮类紫外线吸收剂效果好;
1·Nanosized nickel based catalysts can be used to carry out the hydrogenation of styrol and benzophenone at normal temperature and pressure.
常温常压下,纳米级的镍基催化剂对苯乙烯和二苯甲酮分别有催化加氢活性。
2·The kinetics of thiol-ene reaction is studied by Fourier Transform Infrared when benzoin dimethyl ether, benzoin ethyl ether, benzoin butyl ether, benzophenone and ITX were used as photosensitizer.
为研究硫醇烯光固化组成物的反应机理,选用安息香双甲醚、安息香乙醚、安息香正丁醚、二苯甲酮和噻吨酮为光敏剂,用红外光谱法研究了硫醇烯的光化学反应动力学。
3·The maximum UV absorption wavelength of polymerizable photoinitiator shifted toward long wavelength, and the residues of light-cured were far less than benzophenone.
可聚合光引发剂的最大紫外吸收波长均发生红移,光固化残留量远远小于二苯甲酮。
