[實施例]
實施例及比較例
以滾筒摻合機混合表1所示的組成的各成分後，使用 擠壓機進行熔融混煉，得到丸粒狀的樹脂組成物。使用這些組成物，以下述方法進行洗淨試驗。將結果顯示於表1。
於射出成形機(住友重機械工業公司製「SH100」；圓筒溫度230℃)將1kg的HDPE的紅色著色品(紅色色素濃度0.5%)作為先行使用樹脂進行射出成形。
之後，使用表1的各組成物，重複計量與射出的操作，以紅色消失的時間點作為洗淨結束，並藉由到此為止的組成物的使用量(kg)來評價洗淨性。
又，洗淨結束後，在流洗AS樹脂(DAICEL POLYMER股份有限公司製的CEVIAN N 050SF)時，以確認先行使用樹脂(為前料之HDPE)的紅色是否出現來評價洗淨性(前料有無殘留)。
