Abstract
A method for drying polyolefin-containing particles includes a drying step of supplying polyolefin-containing particles to a drying container, supplying a drying gas to the drying container, and drying the polyolefin-containing particles in the drying container. In the drying step, a numerical value determined by the following formula (a) is 441 or more and 600 or less.38.0×[η]CXIS[dL/g]−0.500×CXIS content[% by mass]+1.20×particle temperature during drying[K]+3.29×drying time[hr] Formula (a):
