Abstract

"SUPERABSORVENTES, PREPARAçãO DOS MESMOS E SEU USO". A presente invenção se relaciona a superabsorventes compostos de policarboxipolissacarídeos pós-reticulados superficialmente tendo excelentes propriedades de absorção, estáveis ao envelhecimento, mesmo quando submetidos a carga, elevada resistência ao atrito e biodegradabilidade, sendo seu uso destinado à absorção de água, fluidos aquosos ou de soro e também sangue. é também descrito um método de produção, que é imune a mudanças na qualidade da matéria prima e que provê qualidade de produto consistente.
