Abstract: The present disclosure provides novel methods of producing a composition, such as, but not limited to, a polyimide composition. 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.

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).
