Abstract
Patente de Invenção: <B>"FORMULAçãO DE POLICARBONATO E SUPORTE PARA PASTILHAS DE SEMICONDUTORES QUE é OPACO A DETERMINADOS COMPRIMENTOS DE ONDA DE LUZ"<D>. Trata-se de uma composição aromática e dos artigos produzidos a partir dela que têm menos de 300 partes por bilhão de impurezas iónicas, em particular íons de sulfato e cloreto, preparada mediante a desvolatilização das impurezas iónicas de uma composição de policarbonato que emprega um meio aquoso de cerca de 1% em peso com base no peso da composição de policarbonato. De preferência a desvolatilização é executada em um extrusor durante a composição da composição de policarbonato e de preferência sob um vácuo. Além disso, os filamentos extrudados de resina de policarbonato são resfriados bruscamente em um banho da água que tem um teor de íons de sulfato e cloreto de menos de 300 ppb cada um.
