## Abstract Formaldehyde resins (FR) at 1/1/2 molar ratios of monomers (Clβphenol/amino monomers/__p__βformaldehyde) were synthesized under acid catalysis. The obtained resins were characterized using elemental analysis, FTIR and RMN spectroscopic methods, being used as crosslinking agents for epox
## Abstract **Summary:** Novel multifunctional formaldehyde resins bearing diaminodiphenylmethane groups are synthesized by the polymerization of a mixture of diaminodiphenylmethane (DDM), __o__βcresol (__o__βCz), and cyclohexanone (CH~x~) with formaldehyde (FA) (at a molar ratio of monomers/formal
## Abstract A multifunctional epoxy tetraglycidyl dibenzmethyldiamine and triglycidyl benzylamine were blended, respectively, into impregnation resin, which mainly consists of diglycidyl ether of bisphenol A (DGEBA) and acid anhydride hardener. This resin is expected to impregnate HTβ7U superconduc
## Abstract The curing behavior and thermal properties of bisphenol A type novolac epoxy resin (bisANER) with methylhexahydrophthalic anhydride (MHHPA) at an anhydride/epoxy group ratio of 0.85 was studied with Fourierβtransform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC),
