Abstract

The invention provides a method for preparing a resin pellet which contains an insect-repellent compound at a desired concentration, by reducing the loss of the insect-repellent compound in the course of preparing the insect-repellent compound-containing resin pellet. The invention relates to a method for preparing an insect-repellent compound-containing resin pellet, said method comprising the steps of mixing porous particles impregnated with an insect-repellent compound with an ethylene based resin satisfying the following condition (1) so that the ratio of said porous particles impregnated with said insect-repellent compound/said ethylene based resin is 20 to 60 wt.%/40 to 80 wt.%, melt-kneading the resulting composition with a twin-screw extruder, and extruding the composition as a strand, and cutting the strand into pellets of the insect-repellent compound-containing resin, wherein said condition (1) of said ethylene based resin is that the ratio of (η1/η2) is from 1.8 inclusive to 3 inclusive, in which η1 is the melt viscosity of the ethylene based resin at 200°C and at a shear rate of 120 sec-1, measured with a capillary rheometer, and η2 is the melt viscosity thereof at 200°C and at a shear rate of 1,200 sec-1.
