ENLARGED POWDER PARTICLES OF CRYSTALLINE POLYOLEFIN AND METHOD OF PRODUCING THE SAME ABSTRACT OF THE DISCLOSURE Enlarged powder particles of crystalline polyolefin and a method of producing the same are disclosed. These enlarged powder particles are obtained from the welding of crystalline polyolefin powder particles with one another at a mutual welding temperature, while the powder particles are subjected to the rate of mutual travel which is sufficient to prevent the conglomeration. These crystalline polyolefin powder particles to be enlarged have an average particle size of smaller than 30 meshes and a viscosity-average molecular weight of at least 50,000 and are prepared by one-step or multi-step suspension polymerization or gas phase polymerization.
