Abstract

"MéTODO PARA CONTROLE DAS PROPRIEDADES DO PRODUTO POLìMERO DE UM PROCESSO DE POLIMERIZAçãO" A presente invenção refere-se a um método para monitoramento da taxa de evolução de espécies voláteis durante polimerizações e uso daquele método para efetuar aperfeiçoamentos de processo e de produto. Particularmente, a presente invenção é útil para o aperfeiçoamento da produtividade do processo e da qualidade do produto na produção de poliamidas, tanto contínua como por batelada. A presente invenção fornece um método para controle das propriedades do produto polímero de um processo de polimerização, compreendendo o processo pelo menos meios para controle de pelo menos um parâmetro de entrada do processo e um meio de ventilação dos gases gerados durante a polimerização, formando assim um fluxo de gás de ventilação, compreendendo o método: desvio de pelo menos uma porção do fluxo de gás de ventilação para um meio de análise de composição; análise da porção desviada do fluxo de gás de ventilação, a fim de determinar a concentração de pelo menos um componente do fluxo de gás de ventilação; determinação de uma taxa de perda de pelo menos um componente do fluxo de gás de ventilação; comparação da taxa de perda com um objetivo previamente determinado, a fim de fornecer uma indicação da ação corretiva necesária; e execução da ação corretiva indicada.
