摘要： A high-performance prepolymerized solid catalyst is prepared by polymerizing an olefin onto an olefin polymerization catalyst in a heterogeneous system under irradiation with an elastic wave, wherein the olefin is prepolymerized in an amount of not less than 0.1 g based on 1 mmol of a transition metal contained in the olefin polymerization catalyst. The elastic wave is preferably an ultrasonic wave. In a process for heterogeneous polymerization of an olefin, an olefin is subjected to slurry polymerization or gas phase polymerization in the presence of the prepolymerized solid catalyst. In a process for heterogeneous polymerization of an olefin, an olefin may be polymerized onto the olefin polymerization catalyst in a heterogeneous system under irradiation with an elastic wave to prepare polyolefin. Therefore, the heterogeneous polymerization of an olefin can be stably conducted and polyolefins of uniform property and high quality can be obtained.
