Abstract

"PROCESSO PARA A PRODUçãO CONTìNUA DE TEREFTALATO DE POLIBUTILENO A PARTIR DE áCIDO TEREFTALATO DE 1,4-BUTANODIOL". A invenção refere-se a um método para a produção contínua de tereftalato de polibutileno a partir de ácido tereftálico e de 1,4-butano diol, que compreende os seguintes estágios: a) esterificação direta de ácido tereftálico com 1,4-butano diol em uma cascata de reator de, pelo menos, dois reatores, e) pré-condensação do produto de esterificação obtido no estágio a), f) policondensação do pré-condensado obtido no Estágio b), em que a temperatura da cascata do reator no estágio a) é progressivamente diminuída durante a sua operação.
