1-Benzyl-3-methyl-imidazolium hexafluoroantimonate (BMH) was newly synthesized and characterized with FT-IR, 1H-NMR. We synthesized catalysts fulfill requirements for a rapid cure at a moderately elevated temperature in curing the epoxy resin for neat diglycidyl ether bisphenol A (DGBEA). The cure behavior of this resin was investigated at elevated temperature and cure temperature in the presence of 0.5, 1.0, 2.0 wt% of 1-benzyl-3-methyl-imidazolium hexafluoroantimonate (BMH) by mean of differential scanning calorimeter (DSC). Chemical conversion as function of temperature and amount of BMH (0.5, 1.0, 2.0 wt%) were determined from DSC. It was found that BMH were superior latent thermal catalyst for catinonic curing which have a good thermal stability.

ABSTRACTWe report the dependences of the degrees of tri- or bi-axial orientation on strength of applied magnetic fields of modulated rotating field (MRF) for twinned ErBa2Cu3Oy (Er123) powder samples oriented in epoxy resin under various MRF conditions. Introduction of a pulverization process in the Er123 powders improved the degrees of inplane orientations, and is effective for enhancing the inplane magnetic anisotropy of Er123 grains with twin microstructure. Formation of inhomogeneous domain structure is a dominant factor of the enhancement, and the present study indicates possibility of tri- or bi-axial orientation of the twinned Er123 grains even under relatively low MRF conditions around 1 T.
