Abstract
A reversible crosslinking reactant composition is provided. The composition includes at least one furan-group-containing oligomer having a structure represented by Formula (I) and a bismaleimide compound having a structure represented by Formula (II), wherein the equivalent ratio of the furan group of the furan-group-containing oligomer having a structure represented by Formula (I) to the maleimide group of the bismaleimide compound having a structure represented by Formula (II) is from 0.5:1 to 1:0.5.
