PROBLEM TO BE SOLVED: To provide a method for producing side-chain crystalline polyolefin powder, with which the powder of the side-chain crystalline polyolefin, obtained by polymerizing anα-olefin, is produced directly from the state of a molten liquid with a simple apparatus at low cost with high efficiency. SOLUTION: In the method for producing side-chain crystalline polyolefin powder, a side-chain crystalline polyolefin is prepared by polymerizing a 10-50Cα-olefin, and the molten side-chain crystalline polyolefin is cooled and simultaneously granulated.
