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
A process for the solid phase polymerization of polyester comprising the steps of providing a crystallizer, introducing cold amorphous polymer to the crystallizer providing a source of infrared radiation, heating said polymer by applying infrared radiation thereto, and controlling the degree of heating whereby said polymer reaches a crystallization temperature without exceeding the polymer melting point.
