Abstract

"POLìMEROS SUPERABSORVENTES TENDO RETICULADORES DE SUPERFìCIE ATIVáVEIS POR RADIAçãO E MéTODO PARA FABRICAçãO DOS MESMOS". A presente invenção refere-se a partículas de polimero superabsorvente com reticulação de superfície otimizada, e a seu uso em artigos absorventes. As partículas de polímero superabsorvente da presente invenção compreendem uma resina hidroabsorvente e o produto de reação de um reticulador de superfície ativável por radiação, sendo que o produto de reação do reticulador de superfície ativável por radiação está presente nas superfícies das partículas de polímero superabsorvente. O reticulador de superfície ativável por radiação compreende ao menos dois grupos R ativáveis por radiação, os quais estão ligados de modo covalente um ao outro, ou a ao menos um grupo espaçador S. Além disso, a invenção refere-se a um processo para fabricação dessas partículas de polímero superabsorvente.
