摘要： The present invention provides a process which enables easy and inexpensive preparation of alkylenebismelamines usable as components for forming resin materials, particularly aminoplasts, and flame retardants. The present invention is a process for preparation of alkylenebismelamines wherein the alkylene is a linear or branched C2-10 one by reacting an alkylenediamine wherein the alkylene is a linear or branched C2-10 one with melamine in the presence of an acidic catalyst under heating, characterized in that the amount of melamine is at least twice that of the alkylenediamine by mole.
