Abstract

"PROCESSO CONTìNUO PARA A PRODUçãO DE POLI(TRIMETILENO TEREFTALATO)". A presente invenção refere-se a um processo contínuo para a produção de poli(trimetileno tereftalato). De acordo com o processo, uma mistura de alimentação líquida compreendendo bis-3-hidroxipropil tereftalato e/ou poliésteres de baixo peso molecular de 1,3-propanodiol e de ácido tereftálico, sendo que a mistura de alimentação líquida tem uma razão molar entre os grupos propileno e os grupos tereftalato de 1,1 a 2,2, é alimentada em um pré-polimerizador. O bis-3-hidroxipropil tereftalato e os poliésteres de baixo peso molecular são polimerizados continuamente para formar um pré-polimero de poli(trimetileno tereftalato) e uma primeira corrente de subprodutos gasosos. O pré-polimero de poli(trimetileno tereftalato) com viscosidade relativa de pelo menos cerca de 5 é removido continuamente do pré-polimerizador e passado continuamente para um polimerizador final, no qual é polimerizado continuamente para formar um poli(trimetileno tereftalato) de peso molecular elevado e uma segunda corrente de subprodutos gasosos. O poli(trimetileno tereftalato) de peso molecular elevado que tem uma viscosidade relativa de pelo menos cerca de 17 é removido continuamente do polimerizador final.
