Abstract
Se describe ácido polianhidroaspártico entrelazado novedoso que es el producto de la reaccion de una polisuccinimida con triaminononano (TAN); dependiendo de la cantidad del agente de entrelazamiento empleado, se producen composiciones de diferentes grados de entrelazamiento; la relacion molar 3 a 1 de polisuccinimida a TAN provee un material insoluble en agua y una relacion molar de 102 a 1 da un material soluble en agua al 28% en peso; dichos compuestos encuentran utilidad como espesantes, desfloculadores, floculadores y absorbentes de agua.
