Abstract

La presente invención se refiere a un método para fabricar papel, caracterizado porque comprende agregar una composición de papel acuosa de alrededor de .0227 a unos 9.08 Kg/Ton (0-05 a unas 20 libras/tonelada), en base a peso seco, de sólidos de composición de papel, de una microperla polimérica orgánica iónica, siendo la microperla menor de unos 750 nanometros de diámetro si está crosvinculada y menor de 60 nanometros de diámetro si no está crosvinculada y es insoluble en agua, siendo la ionicidad de tal microperla de por lo menos 1 por ciento, pero por lo menos 5 por ciento si está crosvinculada, es aniónica y se usa por si sola.
