Method for enhancing crystallinity of polycarbonates |
| abstract |
The crystallinity of an amorphous precursor polycarbonate is enhanced by contact in the liquid or vapor state with a non-solvent which may be water, an alkanol or a mixture thereof and which is dialkyl carbonate-free. Contact temperatures are at least about 75 °C and are further defined by the relationship Tc≥Tb-z, wherein Tc is the contact temperature, Tb is the boiling point of the non-solvent at the contact pressure employed (both in degrees C) and z is a constant whose value is 60. |
