摘　　要：Some new factorizations of unitons into Lie groups are established via singular Darboux transformations. The factorization processes for Grassmannian unitons are also considered. Furthermore, a purely algebraic method for constructing Grassmannian unitons is presented.Some new factorizations of unitons into Lie groups are established via singular Darboux transformations.
