Abstract
Un proceso para la preparación de un gel de copolímero reticuladode anhídrido maleico y alquil vinil éter, que comprende: (a) preparar en una solución acuosa, una mezcla copolímero de alquil vinil éter/anhídrido maleico y un agente poliol de reticulación; (b) reaccionar la mezcla a una temperatura de desde 50 hasta 90°C; y luego (c) recuperar el producto de gel de la mezcla de reacción.El proceso de la reivindicación 1, en el cual el agente poliol de reticulación es glicerina o sorbitol y la reacción de agente poliol de reticulación de glicerina o sorbitol con respecto al copolímero disponible para la reticulación está en una relación de peso de por lo menos 40:1
