ベトついており、押出機への供給がスムーズに行かず、
シート状成形体が得られなかった。Comparative Example 5 An ethylene-vinyl acetate copolymer (Evacy H2020 manufactured by Sumitomo Chemical Co., Ltd.) was used as the synthetic resin, and the l-ethynyl-2-methyl-2-pentenyl chrysanthemate content was shown in Table 3. Pelletization was carried out in the same manner as in Example 1 except that. The surface of the pellets obtained was sticky, making it difficult to feed them to the extruder.
No sheet-like molded product was obtained.
実施例７
綱状成形体のストランド径４−一とした以外は、実施例
２と同様にして、成形体を製造した。Example 7 A molded body was produced in the same manner as in Example 2, except that the strand diameter of the rod-shaped molded body was 4-1.
第３表に示す通り、薬剤揮散および殺虫効力の長期持続
性は良好であった。As shown in Table 3, the long-term persistence of chemical volatilization and insecticidal efficacy was good.
比較例６
合成樹脂としてエチレン−メチルメタクリレート共重合
体（住友化学工業■製アクリフ）ＷＨ２０２）を用い、
綱状成形体のストランド径０．２−とした以外は、実施
例２と同様にして、成形体を製造した。Comparative Example 6 Using ethylene-methyl methacrylate copolymer (ACLIFF WH202 manufactured by Sumitomo Chemical Co., Ltd.) as a synthetic resin,
A molded body was produced in the same manner as in Example 2 except that the strand diameter of the rope-shaped molded body was 0.2-.
第３表に示す通り、薬剤揮散および殺虫効力の長期持続
性は共に不良であった。As shown in Table 3, both chemical volatilization and long-term sustainability of insecticidal efficacy were poor.
本発明の薬剤徐放性樹脂成形体は、防殺虫用として広範
