Calorimetric investigation of curing of some new polyhydroxy epoxy resins

The curing reactions of two new polyhydroxy epoxy resins, i.e. 1,3-bis(2,4,6-trimethylol phenoxy)propan-2-ol (I) and 1,3-bis[4-(3,5-dimethylol-4-hydroxyphenyl trichloroethylidenyl)-2,6-dimethylol phenoxy]propan-2-ol (II) were investigated with differential scanning calorimetry (DSC) either isotherma...

Description
Summary:The curing reactions of two new polyhydroxy epoxy resins, i.e. 1,3-bis(2,4,6-trimethylol phenoxy)propan-2-ol (I) and 1,3-bis[4-(3,5-dimethylol-4-hydroxyphenyl trichloroethylidenyl)-2,6-dimethylol phenoxy]propan-2-ol (II) were investigated with differential scanning calorimetry (DSC) either isothermally or at a constant heating rate. The thermosetting characteristics were studied at several different temperatures (110–150° C). The activation energies of the setting reactions were determined; these were equal to 60.14 and 89.12 kJ mol −1 for the resins I and II, respectively. Two types of curing reactions were observed; dehydration and dehydroformylation reactions.
