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. |
