ABSTRACT:
Packaging and/or storing atactic polypropylene or other amorphous poly alpha olefins is accomplished by first heating a mass of the olefin material to a molten state and then cooling the molten mass of olefin material to an extrusion temperature. Next, the formless mass of atactic polypropylene is extruded and cut into a succession of pellets. Inert dust-like material is sprayed onto the cutting surfaces and the surface of the olefin material so that the natural tendency of the material to stick to itself and to other objects is avoided.
