Abstract
A system for the solid phase polymerization of polymers comprising a crystallizer, and wherein cold amorphous polymer is introduced to the crystallizer. A source of infrared radiation is associated with the crystallizer, and the polymer is heated by applying infrared radiation thereto. The degree of heating is controlled so that the polymer reaches the crystallization or polymerization temperature without exceeding the polymer melting point.
Claims6
An apparatus for the solid phase polymerization of polymers comprising a crystallizer housing, inlet means for receiving cold amorphous polymer into the crystallizer and outlet means for discharging processed polymer from the crystallizer, at least one opening defined by the crystallizer housing, polymer present in the housing being exposed to said opening, infrared radiant heating means mounted in said opening, said radiant heating means including radiation generating lamps and a radiation-transmitting window whereby polymer being processed is heated in the crystallizer by means of said radiant heating means, and means for controlling the heat applied to the polymer by said radiant heating means.
