Abstract

resumo método para a preparação de um polímero superabsorvente a presente invenção refere-se a um método para a preparação de um polímero superabsorvente. o método para a preparação de um polímero superabsorvente de acordo com a presente invenção compreende as etapas de: preparação de um polímero de hidrogel através da realização de uma polimerização térmica ou uma fotopolimerização de uma composição de monômeros incluindo um monômero insaturado à base de etileno solúvel em água e um iniciador de polimerização; secagem do polímero de hidrogel; pulverização do polímero seco; mistura do polímero pulverizado com um agente de reticulação superficial e uma partícula de polímero que possui uma estrutura casca-núcleo; e realização de uma reação de reticulação superficial. de acordo com a presente invenção, o polímero superabsorvente que apresenta permeabilidade melhorada pode ser obtido através da adição da partícula de polímero durante a reticulação superficial.
