Abstract

Patente de Invenção: <B>''PROCESSO PARA POLIéSTERES''<D>. Esta invenção refere-se a um processo para a preparação de um poliéster insaturado, processo este que compreende (i) reagir um diol orgânico com um carbonato de alquileno cíclico na presença de um primeiro catalisador para formar desse modo um polialcóxi diol, e (ii) opcionalmente adicionar uma quantidade adicional de carbonato de alquileno cíclico na presença de um segundo catalisador, e (iii) subseq³entemente policondensar a mistura resultante com ácido dicarboxílico.
