## Abstract Resoles were prepared separately with different phenols, with formaldehyde having phenolβtoβformaldehyde mole ratio of 1:2 in basic medium at 70Β°C. These resoles were physically blended with different weight percentages of diglycidyl ether of bisphenolβA (DGEBA)βepoxy resin. The blends

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
## Abstract Epoxy resin was cured with diethylaminopropylamine (DEAPA) in amounts ranging from 10% to 50% of stoichiometric amount. The yield strength of resulting thermosets formed by heat curing at 75Β°C is found to increase with decreasing amount of hardener. This is attributed to a more densely
Bisphenol A-based benzoxazine that contained oligomers (oligo-Ba) was prepared from bisphenol A, formaline, and aniline. Curing reaction of oligo-Ba with bisoxazoline and the properties of the cured resin were investigated. Consequently, the ring-opening reaction of benzoxazine ring occurred, and th
