Abstract
Description
本方法の1つの好ましい形態においては、照射済みバルク材料固体は熱可塑性ポリマーの粒子(粉末、ペレット、チップ等)からなる。より詳細には、このポリマーの例としてはポリエチレン、ポリ塩化ビニル、ポリプロピレン、ポリテトラフルオロエチレン、ポリエチレンテレフタラート、ポリブチレンテレフタラート、ポリアミド、エチレン酢酸ビニル、熱可塑性ポリウレタン、クロロスルホン化ポリエチレン、ポリエステル、ポリフッ化ビニリデン、エチレンテトラフルオロエチレン、エチレンクロロトリフルオロエチレン、塩素化ポリ塩化ビニリデン、フッ化エチレンプロピレン、フルオロエラストマー、熱可塑性ポリエステルエラストマー、ネオプレンゴム、シリコーンゴム、スチレン−ブタジエンゴム、及びエチレン−プロピレンゴムが挙げられる。
下記は、事前に照射済みの材料固体を熱媒液で直接熱処理する一例である。本例では最終生産物はメルトインデックスレベルが上昇したフッ化エチレンプロピレン(FEP)ポリマー樹脂の粒子である。メルトインデックスレベルの上昇は特定の用途で好まれる。この場合、FEPを照射するのはポリマー鎖の切断を引き起こし、それによってメルトインデックスを所期のレベルに上昇させるためである。次の熱処理は所望のメルトインデックスが得られてその後維持されるような次の時点で、鎖の切断反応を失活させるために用いられる。従来ならば、FEP粒子はガス環境下での熱処理のために熱対流炉に入れられていた。
事前に照射済みの材料固体を熱媒液を用いて熱処理するもう1つの例は、架橋超高分子量ポリエチレン(UHMWPE)の生成である。この場合、ポリマーの長期劣化を防ぐために、照射工程中に生じるフリーラジカルを、熱処理により照射架橋済みUHMWPE固体材料から除去する必要がある(米国特許第6641617号及び第7714036号を参照)。UHMWPE材料固体は酸化反応を制限するために低酸素環境に置くことが多い。低酸素環境に置かない場合は照射工程中に起こる結合の切断により、ポリマー固体中に酸化反応が生じる恐れがある。従来ならばUHMWPEは予め照射した熱処理のために真空密封包装のままで熱対流炉に入れられていた。
事前に照射済みの材料固体を熱処理するもう1つの例であって、その固体材料がポリマーであり、熱媒液を使用する例は、長鎖分岐ポリプロピレンの生成である。この場合、熱処理の目的は(1)長鎖分岐ポリプロピレンの分岐が作れるようにすること、及び(2)フリーラジカルを失活させて、分岐反応を終わらせることである。
事前に照射済みの材料固体を熱媒液を用いて熱処理するもう1つの例は、ポリテトラフルオロエチレン(PTFE)微細粉末又はマイクロ(微小)粉末の生成である。PTFE材料固体(多くの場合、屑PTFE、再利用PTFE又は規格外PTFE)に照射してPTFEポリマーの分子量を減少させると、これにより次にPTFEを粉砕又は研削して微細粉末にすることができるようになる。次の熱処理の1つの目的は照射により起動したフリーラジカルを介して、鎖切断反応を熱的に促進し継続することにより、分子量を更に大きく減少させることである。照射後にPTFEを熱処理する従来の方法(米国特許第4220511号参照)は、例えば250℃で6時間、PTFEを熱対流炉に入れることである。
