Abstract

Se preparo una polisuccinimida de peso molecular variable mediante la polimerizacion térmica de ácido aspártico en presencia de un agente deshidratante que contiene azufre, empleando una variedad de mezclas de reaccion y de condiciones de reaccion. Los agentes deshidratantes de trioxido de azufre y precursores de trioxido de azufre por descomposicion térmica son los preferidos para este proposito. La presencia de un depurador de ácido dentro de la mezcla de reaccion es deseable y conduce a una polisuccinimida de peso molecular relativamente elevado, mientras que la presencia de un depurador ácido da por resultado una polisuccinimida de peso molecular relativamente inferior.
