Abstract
"PRODUTOS DE PAPEL TENDO RESISTêNCIA A MOLHADO A PARTIR DE FIBRAS E POLìMEROS CELULóSICOS FUNCIONALIZADOS POR ALDEìDO". Trata-se de produtos de papel que possuem resistências iniciais a molhado elevadas. Os produtos de papel compreendem fibras celulósicas tendo grupos aldeído livres, cujas fibras são combinadas com um polímero solúvel em água tendo grupos funcionais que reagem com os grupos aldeído para formar ligações que se unem às fibras. Em uma modalidade preferida, as fibras celulósicas contêm um polissacarídeo no qual os grupos hidroxila de pelo menos uma parte das unidades de repetição do polissacarídeo são grupos cis-hidroxila, sendo que as unidades de repetição preferidas são manose e/ou galactose. De forma similar, o polímero solúvel em água é de preferência um polissacarídeo, no qual os grupos hidroxila de pelo menos uma parte das unidades de repetição do polissacarídeo são grupos cis-hidroxila. Os polissacarídeos preferidos são derivados de um ou mais açúcares selecionados da manose, galactose, alose, altrose, gulose, talose e lixose.
