Copolymer of methyl methacrylate and a methacrylate containing azo chromophores and hydroxy groups was synthesized and thermo crosslinked with toluene 2,4 diisocyanate. Second harmonic generation measurements indicated that networks of the crosslinked polymer stabilize the dipole orientation after electrical poling. 合成了一种甲基丙烯酸甲酯与侧链含有偶氮苯生色团和可化学交联基团-羟基的甲基丙烯酸酯共聚物,这种共聚物和甲苯-2,4-二异氰酸酯(TDI)交联得到的交联网络结构使极化后生色团取向稳定化。
The main production technology and new process development and different process technical - economic analysis of methyl methacrylate ( MM A ) were presented. The worldwide and domestic production capacity and demand status of MMA were reviewed. 介绍了甲基丙烯酸甲酯(MMA)主要的生产技术和开发进展以及各种工艺的技术经济分析,并阐述了国内外MMA的生产能力和需求现状。
