Abstract

"PROCESSO PARA A PREPARAçãO DE POLIéSTER" A presente invenção se refere a um processo para a produção de poliésteres apresentando concentrações de aldeído acético excepcionalmente baixas e boa transparência e que compreende as etapas de: policondensação na fase de fusão, de um monómero de poliéster/mistura oligomérica sob condições suficientes para formar um precursor que possui uma viscosidade intrínseca inferior a 75% de uma máxima viscosidade intrínseca possível; e solidificando o estado do referido precursor sob condições suficientes para aumentar a referida viscosidade intrínseca em pelo menos cerca de 0,05 dl/g.
