摘要
液化MDI是MDI类异氰酸酯的重要品种之一 ,通过控制碳化二亚胺转化率可合成具有不同含量碳化二亚胺、脲酮亚胺等官能团的碳化二亚胺改性MDI,采用凝胶色谱法 (GPC)分析产品 ,同时辅以红外光谱 (IR)
A series liquefied MDI (carbodiimide modified MDI) containing different amount of carbodiimide and uretoinime were synthesized by controlling carbodiimide conversion, samples were analysized by gel chromatogram, by the same time, all peaks in GPC spectrum were detected and determined their corresponding component by infrared spectrum.
