| Abstract: | Five kinds of bisphenol-A diglycidyl ethers made in China were characterized by Matrix-ssisted Laser Desorption Ionization Time of Flight Mass Spectrometry(MALDITOF-MS).The information of their degrees of polymerization was obtained,and the moleculcer structures of different degrees of polymerization components were suggested.Some polymers of chloromethyl oxirane itself were found in these epoxy resins. |
