| Abstract: | Summary Methacrylation of triglycidyl triphenyl methane (via methacrylic acid) has been done using three catalysts: dimethyl dodecyl amine (DMDA), tetrabutyl ammonium bromide (TBAB) and chromium (III) diisopropyl salicylate (Cr Dips). The reaction has been followed by epoxy colorimetric titration, CPG and 1H NMR.This study has shown the superiority of chromium catalysis because of its rapidity and ease of process.Then, these cured products (TACTIX and methacrylated TACTIX) show homogeneous Tg values which are higher than 200°C. |
