The molar mass of monomer A in ith copolymer is wAiMi and the weight-average molar mass of monomer A included in a copolymer is MA=Σ(wAiMi)(wAici)/wAcp. Similarly, we have MB=Σ(wBiMi)(wBici)/wBcp. From the definition, WAcp=ΣWAiCi and WBcp=ΣWBiCi. Let's denote the deviati...
Molar Mass and Chemical Composition 2D Analysis for Thermoplastic ElastomersSamples A and B, that show one narrow main peak in GPC/SEC, reveal in the 2Dseparation several peaks, that co-elute in GPC/SEC. For sample A four peaks are present, while Sample B shows only three peaks.The HPLC ...
chemical formula K2Cr2O7, is an important inorganic compound. It is an orange crystalline solid that can dissolve in water and is used as an oxidizing agent and catalyst. In the chemistry laboratory, it is widely used in analysis and synthetic chemical reactions. So, what is the molar mass ...
