METHOD FOR REDUCING VOLATILE ORGANIC COMPOUNDS IN COMPOSITE RESIN PARTICLES, AND COMPOSITE RESIN PARTICLES

摘要

Disclosed is a method for reducing volatile organic compounds in composite resin particles, which comprises a step wherein composite resin particles containing a polyolefin resin and a polystyrene resin are contained and flowed in a container, and a gas that is at a temperature of from (T - 40)°C to (T - 10)°C when the softening point of the composite resin particles is represented by T°C is blown into the container from the lower portion until the amount of volatile organic compounds contained in the composite resin particles as a whole is reduced to 50 ppm or less.
