The invention relates to a continuous or discontinuous method for producing highly condensed solid-phase polyesters involving a crystallization of a polyester material, this crystallization being effected in the presence of a gas having a dew point of less than or equal to approximately 10°C. The invention also relates to a method for producing polyester shaped bodies while using the obtained polyester material to produce bottles, sheets, films and high-strength fibers. |
