摘要：
A method for fabricating a super absorbent polymers which is powder, insoluble in water, able to absorb water, urine and blood and has low residual monomers and less coloring change. The method includes adding an additive to separate the gel. Wherein, the ferrous ion content of the additive is below 30ppm or the cadmium ion content of the additive is below 20ppm or the transition metal ion content of the additive is below 50ppm. The present invention provides a method to fabricate the super absorbent polymer which has excellent anti-coloring ability and low residual monomer content.本發明係提供一種製造具有極佳之耐黃化性質及低殘存單體含量的高吸水性樹脂的方法,此方法包括利用一種分散劑以增加水凝膠體分散性以提高乾燥效率,其中分散劑的鐵離子含量不超過30ppm,鎘離子含量不超過20ppm,或不飽和單體水溶液的過渡金屬離子合計含量小於50ppm。
