−A−C(=O)−B−C(=O)− I
−A−C(=O)−D−C(=O)− II
ここで、Aはp,p’−Ph−O−Ph基であり、Phはフェニレン基であり、Bはp−フェニレンであり、Dはm−フェニレンである。ポリマー中の式I:式IIの異性体比(通常T:I比と称される)は、ポリマーの全体結晶度を変化させるように選択することができる。T:I比は通常50:50〜90:10の範囲であり、ある実施形態においては60:40〜80:20の範囲である。例えば80:20のような高いT:I比は、例えば60:40のような低いT:I比と比較して高い結晶度を提供する。好ましいT:I比には80:20、70:30及び60:40が含まれ、60:40が特に好ましい。また、T:I比が異なるPEKKポリマーの混合物も本開示の範囲内である。
PEKKペレットを160℃〜300℃の範囲の温度、好ましくは180℃〜290℃の範囲の温度に、少なくとも10%の結晶度を有する半晶質PEKKペレットを製造するのに足りる時間、加熱し;
前記半晶質PEKKペレットを粉砕して約10ミクロン〜約150ミクロンの範囲の中位粒子直径を有するPEKK粉体を製造し;そして
前記PEKK粉体を約275℃〜約290℃、好ましくは280℃〜290℃の範囲の温度に加熱して被熱処理PEKK粉体を製造する。
PEKK反応器フレークを押出機で溶融加工し、この押出物を細断することによって、2〜10mmの直径のペレットにする。押出加工温度は一般的に300〜400℃、好ましくは320〜350℃だった。製造されたペレットは、微細構造において非晶質、即ち結晶度0〜5%だった。
