METHODS AND DEVICES FOR REDUCING OR ELIMINATING DEFECTS IN POLYMER WORKPIECES

摘要

The present disclosure provides novel methods for use in producing a composition, such as, but not limited to, a polyimide composition. Furthermore, the present disclosure provides a novel suspension device for use in such methods. The methods in their most general form comprise providing a workpiece, suspending the workpiece and subjecting the suspended workpiece to processing such that the workpiece undergoes a transformation from a first state to a second state. By maintaining the workpiece in a suspended state during processing, processing-related defects are reduced or eliminated. Using such methods, the present disclosure provides compositions that are have no or reduced processing-related defects. In addition, the compositions are more consistent in chemical and physical properties and are cheaper and more economical to produce (since less product is rejected as unsuitable).
