Abstract

"POLìMERO SUPERABSORVENTE". A presente invenção refere-se a um polímero superabsorvente que compreende uma composição que compreende uma resina polimérica que compreende desde aproximadamente 55 até aproximadamente 99,9% em peso de monómeros que contêm grupo ácido insaturado que pode ser polimerizado, desde aproximadamente 0,001 até aproximadamente 5,0% em peso de agente de reticulação interno e desde 0 até 25% em peso de um agente pré-neutralizador; em que a composição de resina polimérica é pró-neutralizada desde 0 até aproximadamente 50% molar e um polímero de aminopolissacarídeo insolúvel em água, que pode ser inchado em água em que quando o polímero superabsorvente está em contato com uma solução aquosa, a composição de resina polimérica é neutralizada pelo polímero de aminopolissacarídeo de modo que a composição de resina polimérica é neutralizada pelo polímero de aminopolissacarídeo de modo que o polímero superabsorvente tenha um grau de neutralização de aproximadamente 20% molar ou mais do que o grau de pré-neutralização da resina polimérica.
