Abstract
【解決手段】 触媒、酸素及び溶媒の存在下、モノヒドロキシ芳香族化合物を反応させて、ポリ(アリーレンエーテル)を形成する段階と、ポリ(アリーレンエーテル)を、ポリ(アルケニル芳香族)と混合して、混合物を形成する段階と、混合物から、ポリ(アリーレンエーテル)及びポリ(アルケニル芳香族)を含むポリマー材料を得る段階と、モノヒドロキシ芳香族化合物、溶媒、ポリ(アリーレンエーテル)、ポリ(アルケニル芳香族)、混合物、ポリマー材料又はこれらの組合せを精製して、視認し得る粒状不純物を実質的に含まないポリマー材料を得る段階とを含む、ポリマー材料の製造方法。ポリマー材料は、データ記憶媒体の用途に使用するのに適している。
Description
ポリサリチレートによるポリ(アリーレンエーテル)の封鎖は、ポリ(アリーレンエーテル)鎖中に存在するアミノアルキル末端基の量を低下させることも考えられる。アミノアルキル基は、ポリ(アリーレンエーテル)を生成するプロセスでアミンを用いる酸化カップリング反応の結果である。ポリ(アリーレンエーテル)の末端ヒドロキシ基に隣接するアミノアルキル基は、高温で分解され易い。この分解は、第一もしくは第二アミンの再生と、キノンメチド末端基の生成をもたらすと考えられ、即ち2,6−ジアルキル−1−ヒドロキシフェニル末端基が生成される可能性がある。アミノアルキル基を含有するポリ(アリーレンエーテル)の、ポリサリチレートによる封鎖は、そのようなアミノ基を除去することによって、ポリマー鎖の封鎖末端ヒドロキシ基をもたらし、2−ヒドロキシ−N,N−アルキルベンズアミン(サリチルアミド)の形成をもたらすことが考えられる。アミノ基の除去及び封鎖は、高温に対してより安定なポリ(アリーレンエーテル)を提供し、それによって、ポリ(アリーレンエーテル)の処理中に、ゲルや黒色斑点などの分解生成物がより少なくなる。
ポリ(アリーレンエーテル)は、通例、触媒系、酸素及び溶媒の存在下、1種以上のモノヒドロキシ芳香族化合物の酸化カップリングによって製造される。ポリ(アリーレンエーテル)の合成に使用されるモノヒドロキシ芳香族化合物に、別段制約はない。適切なモノヒドロキシ芳香族化合物には、以下の式(II)のものがある。
重量比40/60の、ポリフェニレンエーテル(PPE、0.33IV PPE粉末、GE Plasticsから入手可能)及びポリスチレン(xPS、L3050)のブレンドを、以下の手順に従って製造した。予熱した(約125℃)窒素ブランケットによる、撹拌量の試薬級オルトジクロロベンゼン(ODCB)に、PPE粉末を72.6kg及びxPSを108.9kg添加して、20重量%の固形分を含有する溶液を形成した。この溶液を約170℃に加熱して、5μmサイズのフィルタバッグに通して重力濾過した。
