Abstract

"PROCESSO PARA PREPARAR RESINAS ABSORVENTES DE áGUA". A invenção diz respeito a um método para produzir resinas absorventes de água com base em ácido acrílico. O ácido acrílico bruto é primeiro isolado dos gases de reação da reação de fase gasosa catalítica de propano, propeno e/ou acroleína. O dito ácido acrílico bruto é tratado com um removedor de aldeído e o ácido acrílico puro é separado por meio de destilação do ácido acrílico bruto tratado. O ácido acrílico puro pode depois ser submetido imediatamente à polimerização de radical.
