摘要：

We demonstrate that the coproduct of D = 2 and D = 4 quantum kappa-Poincare algebras in a classical algebra basis cannot be obtained by a cochain twist depending only on Poincare algebra generators. We also argue that the nonexistence of such a twist does not imply the nonexistence of a universal R-matrix.
