Abstract
La polisuccinimida se prepara al hacer reaccionar un acido dicarboxilico de C2 no saturado o anhidrido del mismo, por ejemplo, acido maleico, acido fumarico, y anhidrido maleico, con una sal de amoniaco particulada que es termicamente desdoblable para liberar amoniaco. La reaccion se lleva a cabo a aun temperatura que se encuentra por encima de la temperatura de descomposicion termica de al sal de amoniaco y durante un periodo de tiempo que es suficiente para que el acido o anhidrido reacciones con el amoniaco liberado a partir de la sal de amoniaco y para que ocurra la polimerizacion. El presente metodo evita los problemas de la tecnica anterior para controlar las perdidas de amoniaco y el retiro de agua. la polisuccinimida producto puede hidrolizarse facilmente en acido poliaspartico o una sal del mismo si se desea.
