Description
15mlのLDPE白色半透明ボトル(直径2.4cm、高さ5.8cm)にガス相スルホン化を施した。事前にスルホン化されたボトルは、硫黄元素が測定不可能であることを示し、スルホン化ボトルは、X線光電子分光法(XPS)により求めた6.9原子百分率の表面での硫黄元素の含有量を示した。スルホン化ボトルを目視により、内側も外側も変色して黒になったことを観察した。ボトルを脱イオン(DI)水(18メガオーム)で濯いだ。スルホン化ボトルを20重量%のOptima(商標)硝酸(Fisher Scientific)で充填し、ボトルを7日間にわたって振盪した。硝酸は、黄色になり、ボトルの内壁の変色は、ほぼ取り除かれ、スルホン化副産物の除去を示した。次に、ボトルをDI水(18メガオーム)で濯ぎ、XPSで測定した表面の硫黄含有量は、3.4原子百分率であった。アクリル樹脂と有機溶媒との混合物を含む、10mlのOC(商標)3050 Immersion Topcoat Material(Dow Electronic Materials,Marlborough,MA)をボトルに加えた。ボトルを7日間にわたって振盪し、Agilent 8800 ICP-MSシステムを用いて金属分析を行った。ICP金属分析は、全ての実施例に対してボトルからの2つの試料を含んだ。結果を表1に示す。
15mlのLDPE白色半透明ボトル(直径2.4cm、高さ5.8cm)を20重量%のOptima(商標)硝酸(Fisher Scientific)で充填し、ボトルを7日間にわたって振盪した。次に、ボトルをDI水(18メガオーム)で濯いだ。10mlのOC(商標)3050 Immersion Topcoat Material(Dow Electronic Materials)をボトルに加えた。ボトルを7日間にわたって振盪し、Agilent 8800 ICP-MSシステムを用いて金属分析を行った。結果を表1に示す。
スルホン化して、DI水で濯いだボトルを実施例1で説明したように調製した。10mlのOC(商標)3050 Immersion Topcoat Material(Dow Electronic Materials)をボトルに加えた。ボトルを7日間にわたって振盪し、Agilent 8800 ICP-MSシステムを用いて金属分析を行った。結果を表1に示す。
硝酸で処理し、DI水で濯いだスルホン化ボトルを実施例1で説明したように調製した。10mlのTraceSELECT Ultra TMAH溶液(水に溶かして25重量%)(Fluka)をボトルに加え、1週間振盪した。TMAH溶液は、暗褐色になり、ボトルから取り除いた。ボトルを18メガオームのDI水で濯いで、10mlのOC(商標)3050 Immersion Topcoat Material(Dow Electronic Materials)をボトルに加えた。ボトルを7日間にわたって振盪し、Agilent 8800 ICP-MSシステムを用いて金属分析を行った。結果を表1に示す。
硝酸で処理し、DI水で濯いだスルホン化ボトルを実施例1で説明したように調製した。10mlのOptima水酸化アンモニウム溶液(20重量%)(Fisher Scientific)をボトルに加え、1週間振盪した。TMAH溶液は、暗褐色になり、ボトルから取り除いた。ボトルを18メガオームのDI水で濯いで、10mlのOC(商標)3050 Immersion Topcoat Material(Dow Electronic Materials)をボトルに加えた。ボトルを7日間にわたって振盪し、Agilent 8800 ICP-MSシステムを用いて金属分析を行った。結果を表1に示す。
本発明の容器の再利用に対する適合性を検討するために、スルホン化し、硝酸洗浄して、OC(商標)3050 Immersion Topcoat Material(Dow Electronic Materials)を含有する実施例1で調製したボトルを精製済みの乳酸エチルで濯いだ。次に、ボトルを18メガオームのDI水で濯ぎ、20重量%のOptima硝酸(Fisher Scientific)で7日間処理した。得られた硝酸は、透明のままであった。ボトルを18メガオームのDI水で濯いで、10mlのOC(商標)3050 Immersion Topcoat Material(Dow Electronic Materials)をボトルに加えた。ボトルを7日間にわたって振盪し、Agilent 8800 ICP-MSシステムを用いて金属分析を行った。結果を表1に示す。
