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.Invention Patent: "METHOD TO INCREASE POLYCARBONATE ACRISTALINITY". The crystallinity of an amorphous precursor polycarbonate is increased in the vaporized or liquid state with a non-solvent, which may be water, an alkanol or a mixture thereof and which is free of dialkyl carbonate. The contact temperatures are at least about 75 <198> C and are still defined by the ratio T ~ c ~ <242> T ~ b ~ - z, where T ~ c ~ is the contact temperature, T ~ b ~ is the point boiling point of the non-solvent at the contact pressure used (both at <198> C) and z is a constant whose value is 60.
