摘要：Packaging and/or storing atactic polypropylene or other amorphous poly alphaolefins is accomplished by first heating a mass of the olefin material to a molten stateand 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 ofpellets. Inert dust-like material is sprayed onto the cutting surfaces and the surface ofthe olefin material so that the natural tendency of the material to stick to itself and toother objects is avoided.
