Abstract

"PROCESSO PARA DETERMINAR A QUANTIDADE DE POLìMERO DEPOSITADO DE áCIDO (MET)ACRìLICO E/OU éSTERES (MET)ACRìLICOS". é descrito um método não invasivo para a determinação inline e/ou online de polímero separado de ácido (met)acrilico e/ou de ésteres de ácido (met)acrílico por meio de medições de velocidade do som, medições de coeficientes de absorção na faixa do infravermelho, na faixa do infravermelho próximo, na faixa do ultravioleta, e/ou na faixa do visível do espectro de radiação eletromagnética, e de espectroscopia Raman. O citado método permite que os parâmetros de operação sejam controlados em uma maneira específica durante a purificação térmica.
