Abstract

"ESTRUTURA POLIMéRICA TIPO ESPUMA ABSORVENTE DE áGUA, COMPóSITO, PRODUTOS QUìMICOS E PROCESSO PARA SUA PREPARAçãO". A presente invenção se refere a um processo para a preparação de estruturas poliméricas do tipo espuma absorvente de água, sendo que uma composição aquosa (A) contendo: (A1) água, (A2) um ou mais polímeros baseados pelo menos em: (<244>) 55 a 100% em peso de um monómero contendo grupamento ácido, monoetilenicamente insaturado, polimerizado ou seus sais, e em (<244>2) 0 a 45% em peso de um monómero monoetilenicamente insaturado, polimerizado que é copolimerizável com (<244>1), em que a soma das quantidades em peso de (<244>1) e (<244>2) é 100% em peso e em que pelo menos 31, 5% em peso dos monómeros, baseado no peso total dos monómeros (<244>1) e (<244>2), são ácido acrílico ou sais de ácido acrílico, (A3) um ou mais reticulantes, (A4) um ou mais agentes de expansão, (A5) um ou mais tensioativos, (A6) e, opcionalmente substâncias auxiliares adicionais, é espumada, e a composição aquosa espumada é, então, aquecida a uma temperatura na faixa de 50 a 300<198>C, de modo que o polímero (A2) se reticula pelo menos parcialmente e o conteúdo de água (A1) é ajustado para não mais do que 15% em peso, baseado no peso total da estrutura polimérica do tipo espuma que se forma, e a uma estrutura polimérica do tipo espuma absorvente de água obtenível por este processo, a uma estrutura polimérica do tipo espuma absorvente de água, a um compósito compreendendo uma estrutura polimérica do tipo espuma absorvente de água e um substrato, a um processo para a produção do compósito, a compósitos obteníveis por este processo, ao uso da estrutura polimérica do tipo espuma absorvente de água, e a produtos químicos.
