Abstract

POLìMEROS HIDROSSOLúVEIS OU INTUMESCìVEIS EM áGUA, BEM COMO PROCESSO PARA A PRODUçãO E USO DOS MESMOS. A presente invenção refere-se a um processo para a produção de polímeros hidrossolúveis ou intumescíveis em água com teor de monómeros residuais mais baixo, especialmente ã base de ácido acrílico e/ou acrilamida e pelo menos um outro comonómero hidrossolúvel, no qual uma solução de monómeros polimerizadora é tratada o mais cedo possível após alcançar a temperatura máxima da polimerização com radiação eletromagnética, em seguida, o gel obtido é triturado e secado, os polímeros hidrossolúveis ou intumescíveis em água obteníveis conforme o processo como tais, bem como seu uso na indústria de higiene, na indústria de embalagem, na agrotécnica ou na agricultura e horticultura, na indústria de cabos ou na técnica de comunicações, na indústria alimentícia, na indústria de papel e na indústria alimentícia, bem como seu uso como agentes auxiliares de floculaçáo e como fluido de lavagem no transporte de petróleo bruto.
