PROBLEM TO BE SOLVED: To provide an agent-containing resin molded form excellent in moistureproof performance and long-term sustainability of a pharmacodynamic effect.SOLUTION: In an agent-containing resin molded form containing 100 pts.mass of a main material obtained by mixing 0.5 to 5 pts.mass of acid-modified PP resin in 100 pts.mass of PE resin and 0.01 to 1 pt.mass of an agent having a polar group, since the PE resin is modified and has polarity, the main material has affinity to the agent having a polar group and the mutual solubility is improved. As a result, the agent is held in the obtained resin molded form in a long period of time and bleed-out of the agent is inhibited. Further, moistureproof performance inherent to the PE resin is not deteriorated. Consequently, the agent-containing resin molded form excellent in moistureproof performance and long-term sustainability of a pharmacodynamic effect is obtained.COPYRIGHT: (C)2015,JPO&INPIT【課題】防湿性能と薬効の長期持続性とに優れる薬剤含有樹脂成形体を提供する。【解決手段】PE樹脂100質量部に酸変性PP樹脂を0.5~5質量部混合した主原料100質量部と、極性基を有する薬剤0.01~1質量部とを配合した薬剤含有樹脂成形体は、PE樹脂が改質され、極性を持つようになるため、主原料と極性基を有する薬剤とのなじみがよくなり、相溶性が改善される。その結果、得られた樹脂成形体中に薬剤が長期に亘って保持され、薬剤のブリードアウトが抑制される。しかも、PE樹脂が本来有する防湿性能は低下しない。したがって、防湿性能に優れ、かつ薬効の長期持続性に優れる薬剤含有樹脂成形体が得られる。【選択図】図4
