Abstract
The factorization of the universal R-matrix corresponding to so called Drinfeld Hopf structure is described on the example of quantum affine algebra . As a result of factorization procedure we deduce certain differential equations on the factors of the universal -matrix, which allow to construct uniquely these factors in the integral form.
