フィルムを、セルロースアセテート DS 2.45をアセトンに溶解させ、塩基性添加物および任意選択的に抑制剤を加えることによって製造した。結果として生じた混合物を、自動フィルムアプリケータを用いるフィルムキャスティング手順にかけた。フィルムを乾燥させ、カットして小片(6.5cm×6.5cm)にし、小片を枠に取り付け、EN ISO 11721-1に従って土壌に埋めた。1カ月後および2カ月後に、検体を土壌から回収し、粗い堆積物から注意深くきれいにし、重量についておよび目視で喪失面積をについてチェックした。各報告減量および喪失面積は、それぞれ、6つのフィルムの平均であり、土壌と接触していたフィルムの部分に関連している。
フィルムA:15部のセルロースアセテートおよび85部のアセトンから(比較例)
フィルムB:15部のセルロースアセテート、85部のアセトン、0.79部のMgO(最終生成物中5重量%のMgOをもたらす)から

フィラメントA(比較):73部のアセトン中の26.9部のセルロースアセテートおよび0.1部のTiO2からの紡糸液。
フィラメントB:73部のアセトン中の25.6部のセルロースアセテート、1.35部のMgO(最終生成物中5重量%をもたらす)、0.07部のクエン酸(最終生成物中0.25重量%をもたらす)および0.1部のTiO2からの紡糸液。
