Abstract
"MEDIçãO ON-LINE E CONTROLE DAS PROPRIEDADES DE POLìMERO ATRAVéS DE ESPECTROSCOPIA RAMAN". A presente invenção refere-se a métodos que são fornecidos para determinar e controlar as propriedades do polímero on-line em um sistema de reator de polimerização, como um reator de leito fluidizado. Os métodos incluem obter um modelo de regressão para determinar uma propriedade do polímero, o modelo de regressão incluindo cargas de componente principal e contagens de componente principal, adquirir um espectro Raman de uma amostra de poliolefina compreendendo poliolefina, calcular uma nova contagem de componente principal de pelo menos uma porção do espectro Raman e das cargas de componente principal e calcular a propriedade do polímero aplicando a nova contagem de componente principal ao modelo de regressão. A propriedade pode ser controlada ajustando pelo menos um parâmetro de polimerização com base na propriedade calculada do polímero.
