Abstract

"COMPOSIçãO ABSORVENTE, PROCESSO PARA A PREPARAçãO DE PARTìCULAS DE POLìMEROS DE FLUXO LIVRE E ARTIGO ABSORVENTE", compreendendo composições de polímero entumecíveis em água tendo tendências de pó reduzida, isto é, quantidades reduzidas de pós não associados tendo um diâmetro máximo menor ou igual a 10 micra,m e/ou a tendência para gerar quantidade reduzidas de pós não associados tendo um diâmetro máximo menor ou iguakl a 10 micra com o atrito, e um processo para preparar estas composições. Agentes anti-pó hidrofóbicos são usados para atingir o objetivos acima, enquanto mantendo ou aumtenado substancialmente a tensão na superfície de um fluido aquoso em equilíbrio com o polímero e ar.
