To obtain a resin compound for an interlayer in high efficiency without causing blocking and defective cutting troubles by extruding a molten strand of a resin compound for interlayer with an extruder, passing the extrudate through an aqueous dispersion of an ethylene-vinyl acetate copolymer having a specific concentration and pelletizing the cooled strand.

The objective resin compound for an interlayer is composed of 100 pts.wt. of an ethylene-vinyl acetate copolymer or an ethylene-(meth) acrylate copolymer, 5-150 pts.wt. of a hydrocarbon resin and 0.1-10 pts.wt. of a silane coupling agent. The following steps are added in the production of the resin compound. A molten strand of the resin compound extruded with an extruder is cooled by passing through an aqueous dispersion of an ethylene- vinyl acetate copolymer having a solid concentration of 1-20wt.% and the cooled strand is pelletized with a pelletizer.
