以4,4-二-溴二苯甲酮和对苯二胺为单体,在钯催化体系(BINAP/(Pd2(dba)3)作用下得到聚亚胺亚胺酮(PIIK)(Mn=35000,Mw=125000,Mw/Mn=3.57)。通过Materials Studio(MS,version 4.3Accelrys Software Inc.,SanDiego,CA,USA)中的Blends模块对PIIK/Dioxane溶液体系的热致相分离行为进行了计算模拟。模拟结果显示PIIK/Dioxane体系可实现液-液相分离。在理论模拟的支持下,采用热致相分离和冷冻干燥技术成功制备了不同密度的PIIK泡沫,其密度在80～300mg/cm3之间,平均孔径低于5μm。
Polyiminone (PIIK) was obtained under the action of BINAP / (Pd2 (dba) 3) using 4,4-bis-bromobenzophenone and p-phenylenediamine as monomers. 35000, Mw = 125000, Mw / Mn = 3.57) The thermotropic phase separation behavior of the PIIK / Dioxane solution system was determined by the Blends module in Materials Studio (MS, version 4.3 Accelrys Software Inc., San Diego, CA, USA) The simulation results show that the PIIK / Dioxane system can achieve liquid-liquid phase separation.Under the theoretical simulation, the PIIK foam with different densities has been successfully prepared by thermal induced phase separation and freeze-drying, the density is between 80 ~ 300mg / cm3, the average pore diameter of less than 5μm.
