Abstract

Un método para mejorar la resistencia a aplastamiento y reducir la formacion de polvo y la tendencia a formar tortas de las partículas de urea por la adicion de un compuesto orgánico a la urea fundida, en donde al menos un hidrato de carbono y opcionalmente un compuesto de polivinilo se agregan a la urea. La presente también se refiere a una composicion para ser usada como aditivo de urea.
