実施例及び比較例
表１に示す組成の各成分をタンブラーブレンダーで混合後、押出機にて溶融混練し、ペレット状の樹脂組成物を得た。これらの組成物を使用し、下記の方法で洗浄試験を行った。結果を表１に示す。
Examples and Comparative Examples After mixing each component having the composition shown in Table 1 with a tumbler blender, the components were melt-kneaded with an extruder to obtain a pellet-shaped resin composition. Using these compositions, a cleaning test was conducted by the following method. The results are shown in Table 1.
射出成形機（住友重機械工業社製「ＳＨ１００」；シリンダー温度２３０℃）に、先行使用樹脂としてＨＤＰＥの赤色着色品（赤色色素濃度０．５％）１ｋｇを射出成形した。
その後、表１の各組成物を用いて計量と射出の操作を繰り返し、赤色が消えた時点を洗浄終了として、それまでの組成物の使用量(kg)により洗浄性を評価した。
また洗浄終了後にＡＳ樹脂（ダイセルポリマー株式会社製のセビアンＮ ０５０ＳＦ）を流したときに先行使用樹脂（前材であるＨＤＰＥ）の赤色がでるかどうかで洗浄性（前材の残留の有無）を評価した。
On an injection molding machine (“SH100” manufactured by Sumitomo Heavy Industries, Ltd .; cylinder temperature: 230 ° C.), 1 kg of HDPE red-colored product (red pigment concentration: 0.5%) was injection-molded as a prior use resin.
Thereafter, the measurement and injection operations were repeated using each composition shown in Table 1, and when the red color disappeared, the cleaning was finished, and the detergency was evaluated based on the amount (kg) of the composition used so far.
In addition, when the AS resin (Cebian N 050SF manufactured by Daicel Polymer Co., Ltd.) is flowed after the cleaning is finished, the cleaning property (presence / absence of residual material) depends on whether the resin used (HDPE, the previous material) is red. evaluated.

実施例１〜４と比較例１〜８との対比から、本発明の組成物の効果が確認された。
実施例２と、比較例６（（Ｅ）成分を含んでいない）と比較例７（（Ｄ）成分を含んでいない）との対比から、（Ｄ）成分と（Ｅ）成分の両方を含むことによる顕著な効果が確認された。なお、比較例６は、製造途中で（Ｂ）成分が架橋反応を起こして粘度が上昇したため、製造自体ができなかった。
From the comparison between Examples 1 to 4 and Comparative Examples 1 to 8, the effect of the composition of the present invention was confirmed.
From the comparison between Example 2 and Comparative Example 6 (not including (E) component) and Comparative Example 7 (not including (D) component), both (D) component and (E) component are included. The remarkable effect by this was confirmed. In Comparative Example 6, since the viscosity of the component (B) was increased by the crosslinking reaction during the production, the production itself could not be performed.
