Abstract
Disclosed herein are methods for producing polymeric materials which are normally tenacious in their character to such degree that their processing by conventional means is not possible, for example substantially-amorphous polyolefins. By introducing a second catalyst capable of producing a powdery polymer into the polymerization system during production of the sticky polymers, these normally sticky, tenacious polymers are rendered into a form which may be processed using conventional means and equipment.
