Polyolefin polymers are very well known in the art. Methods of manufacturing and/or processing polyolefins are likewise well known in the art. These methods of processing include but are not limited to blow molding, injection molding, pultrusion and pulforming, and extrusion. The problems associated with each of these processes are known, and seeking solutions to these problems, and/or improvements in processing conditions and equipment remains of interest to the art and industry.
For example, it is known that olefinic homopolymers such as high-density polyethylenes (HDPE) and polypropylenes generally have poor processability and poor impact properties. Because of the wide commercial uses of these polymers in various applications such as automotives, households, and. packaging, it is always desirable to discover new methods, additives, and/or equipment which enable these polymers to be better and more economically processed, and to improve the mechanical and other properties of these polymers and/or products made from the polymers.
