ポリオレフィンを含む粒子の乾燥方法

Abstract

To reduce harmful organic compounds.SOLUTION: Provided is a method for drying particles containing a polyolefin(s), comprising a drying step where particles containing a polyolefin(s) are supplied into a drying vessel and a drying gas is fed into the drying vessel to dry the particles containing a polyolefin(s) in the drying vessel, wherein in the drying step, a value obtained by the following formula (a) is from 441 to 600. Formula (a): 38.0×[η]CXIS [dL / g]-0.500×(CXIS content [mass%])+1.20×(particle temperature during drying [K])+3.29×(drying time [hour])SELECTED DRAWING: Figure 1
