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 que compreende 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 possui uma razão molar entre os grupos propileno e os grupos tereftalato de 1,1 a 2,2, é introduzida em um vaporizador ("flasher"). Uma primeira corrente de subprodutos gasosos é vaporizada continuamente e removida do vaporizador, e um produto de reação líquido no vaporizador que tem uma razão molar entre os grupos propileno e os grupos tereftalato de menos de cerca de 1,5 é removido continuamente do vaporizador. O produto de reação líquido no vaporizador é passado continuamente para um pré-polimerizador, no qual é polimerizado continuamente para formar um pré-polimero de poli(trimetileno tereftalato) e uma segunda corrente de subprodutos gasosos. O pré-polimero de poli(trimetileno tereftalato) que tem uma 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 mais elevado e uma terceira corrente de subprodutos gasosos. O poli(trimetileno tereftalato) de peso molecular mais elevado que tem uma viscosidade relativa de pelo menos cerca de 17 é removido continuamente do polimerizador final.
