Abstract: La presente invención se refiere a un proceso para la preparación de polisulfonas con un Índice de Amarillez de acuerdo con DIN 6167 menor a 19 y de polietersulfonas con un Índice de Amarillez de acuerdo con DIN 6167 menor a 30, caracterizado en que la reacción de polimerización se lleva a cabo en solventes apróticos, básicos, usando un agitador mecánico el cual pasa cerca de la pared. La presente invención también se refiere a las polietersulfonas y las polisulfonas que se pueden obtener por primera vez mediante este proceso, y al uso de estos polímeros para la producción de molduras, láminas membranas y espumas.
