Ultrasound Assisted Process for Increasing the Crystallinity of Slow Crystallizable Polymers
In general, the present invention provides a process for increasing the crystallinity of a slow crystallizable polymer. In this process, at least one slow crystallizable polymer is introduced to a pressurized treatment zone along a flow direction, and is subjected, at the pressurized treatment zone, to longitudinal vibrations of ultrasonic waves. In a particularly preferred process, the ultrasonic waves propagate in a direction perpendicular to the flow direction of the at least one slow crystallizable polymer.
