Description
次に、実施例における評価資料の作成方法について説明する。まず、CDと受酸剤を混合し、成形機でパージした。成形機のシリンダー温度は200〜220℃、シリンダー内滞留時間は180秒であった。前記受酸剤としては、酸化マグネシウム、ハイドロタルサイト、炭酸カルシウム、炭酸マグネシウム、水酸化カルシウム、ケイ酸マグネシウムを用いた。酸化マグネシウムについては、マスターバッチについても測定した。マスターバッチのベースレジンには、エチレンアクリル酸エチル共重合体(EEA)を用いた。
パージした樹脂を液体窒素で凍結しこれを粉砕して試料とした。
(発生塩酸の捕集)
捕集液には3ml(1.8mM Na2CO3/1.7mM NaHCO3)を用い、加熱方法は、試料燃焼装置としてQF02(三菱化学社製)を用い、加熱温度240℃、加熱時間3分、雰囲気;酸素/アルゴン;250/100ml/min、試料量は0.3〜0.4gの条件で行った。
(測定)
測定には、正確に測定できるイオンクロマトを使用し、カラム;ASA−SC、流速;1.5m/min、溶離液;1.8mM Na2CO3/1.7mM NaHCO3の条件で行った。分析結果を表2に示す。
