In the biphenol-type epoxy resin cured with catechol novolac (CN), a very weak glass transition and, thus, a very high rubbery modulus were observed. On the other hand, the glass transition was clearly observed in the system cured with phenol novolac (PN). This means that the micro-Brownian motion o

The epoxy resin containing a typical mesogenic group such as biphenol was cured with catechol novolak and aromatic diamines which have neighboring active hydrogens. In the biphenol-type epoxy resin cured with catechol novolak, 4,4-diaminodiphenylmethane, and p-phenylenediamine (PPD), the glass-rubbe
The curing behavior of diglycidyl ether of bisphenol-A (DGEBA) with aromatic diamines having aryl-ether, aryl-ether-carbonyl, and aryl-ether-sulfone linkages was studied using differential scanning calorimetry (DSC). Aromatic diamines such as 1,3-bis ( aminophenoxy ) benzene ( R ) , 1,4-bis ( aminop
