英文摘要 | A combined technique of GPC & MALDI-TOF was used to determine the true molecular weight and distribution of BPA-modified epoxy resin. The technique provided an accurate determination of the Mw (in mass) by MALDI-TOF on fractionates collected from a GPC global curve and these fractionates were used as standards for Mw determinations. This information pertaining to identification on the macromolecular structure may also be used to monitor the reaction and thus to secure the optimum condition especially for the copolymer preparation. |
