Abstract

Patente de Invenção: "MéTODO PARA AUMENTAR ACRISTALINIDADE DE POLICARBONATOS". A cristalinidade deum policarbonato precursor amorfo é aumentada no estado vaporou líquido com um não-solvente, que pode ser água, um alcanolou uma mistura deles e que é isento de carbonato de dialquila. Astemperaturas de contato são pelo menos cerca de 75<198>C esão ainda definidas pela relação T~ c~ <242> T~ b~ - z, em queT~ c~ é a temperatura de contato, T~ b~ é o ponto de ebuliçãodo não-solvente na pressão de contato empregada (ambas em<198>C) e z é uma constante cujo valor é 60.
