Disclosed in this invention are the slow-releasing resin moldings which are the porous bodies obtained by stretching 1.1-10 times the resin compositions comprising 100 parts by weight of a thermoplastic resin, 50 to 400 parts by weight of a filler and an active ingredient in an amount not less than the saturation dissolution rate for the thermoplastic resin, and a process for producing such slow-releasing resin moldings. |
