Abstract
The invention concerns a process for crystallizing a polycarbonate polymer which consists in incorporating to said polycarbonate polymer a finely divided nucleating agent and/or a plasticizer for said polycarbonate polymer, and crystallizing the mixture thus obtained at a temperature higher than the vitreous transition temperature. The semi-crystalline polymer material obtained can be reinforced by adding inorganic fibers.
