Description

The thermally latent polymeric hardener 1 a-d consisting of hemiacetal ester moiety in the polymer back bone was designed, and examined on its thermally latent ability with complex 3 and/or 5 as the crosslinking system of glycidyl phenyl ether (2) and/or 3-ethyl-3-phenoxymethyl oxetane (4). Further, the compound 1 a-d thermally acted as a cross-linker of bisphenol A diglycidyl ether (8) and/or 1, 4-bis {[(3-ethyl-3-oxetanyl)methoxy] methyl} benzene (9). The storage stability of these systems was evaluated in the presence of Lewis acidic complex 3 and/or 5, in which any curing reaction was not observed during 2 months at room temperature.
