New curable compound is liquid state before curing and soften/liquefy in short time after curing at lower temperature than thermal decomposition point

摘要

A curable compound comprising: (a) heat dissociation group(s) that is uninvolved in cross-linkage; and (b) two or more cross-linking groups. A curable compound comprising: (a) heat dissociation group(s) of formula (1-1); and (b) two or more cross-linking groups selected from isocyanate, block isocyanate, alkoxysilyl, epoxy, acid anhydride, amino, latent amino, mercapto and/or carboxyl is new. R<1> - R<3> = H or 1-18C hydrocarbon; X = O or S. An Independent claim is also included for a simple dissociation method of the cured compound by cross-linkage of the prepolymer composition containing cross-linking groups and heat dissociation group(s), heating the heat dissociation group(s) and softening/liquefying the cured compound.
