1)噴霧ノズルを備える窒素流下のパドルミキサー中に、ポリアミド66顆粒を窒素下で導入する。顆粒は、約85℃の温度を有する。撹拌を速度150rpmで開始し、次に、3バールの圧力で、噴霧ノズルを用いて少なくとも1種の熱安定剤を含む水溶液を噴霧する。少なくとも1種の熱安定剤を含む水溶液の噴霧後、任意選択ですすぎ液を噴霧し、顆粒を150rpmの速度で5分撹拌し続ける。その後、このようにして添加した顆粒を窒素の保護下で排出させる。

1.1−Cul/Klの単一水溶液:
200gのCul/Klの単一水溶液を調製するために、予備洗浄し、脱イオン水ですすいでおいた撹拌ミキサーを用い、これに、80gの脱イオン水、次に94.9gのヨウ化カリウム、さらに残りの14.9gの脱イオン水を導入する。混合物を1時間撹拌する。溶解反応は、高度に発熱性である。次いで、10.2gのヨウ化銅を添加した後、混合物を20分間撹拌する。このようにして得られた水溶液を濾過し、褐色のガラス容器に保存する。
200gのCuBr2/KBrの単一水溶液を調製するために、予備洗浄し、脱イオン水ですすいでおいた撹拌ミキサーを用い、これに、120gの脱イオン水、次に58gの臭化カリウム、さらに残りの15.5gの脱イオン水を導入する。混合物を1時間撹拌する。溶解反応は、高度に発熱性である。次いで、6.5gの二臭化銅を添加した後、混合物を20分間撹拌する。このようにして得られる水溶液を濾過し、褐色のガラス容器に貯蔵する。
52重量%のN塩の水溶液からポリアミド6.6を調製し、9ppmの消泡剤(シリコーン組成物)の外部再循環を備える蒸発器内に配置する。0.24MPaの圧力で154.0℃まで加熱することにより、N塩の溶液を濃縮する。蒸発の終了時に、溶液中の溶解種の濃度は、85.0重量%である。次に、この溶液をオートクレーブ内に移す。オートクレーブを加熱して、1.85MPaの自己圧力を達成する。圧力下の重合段階を42分間持続させた後、圧力を大気圧まで徐々に減じる。次に反応器を大気圧で20分間維持するが、このステップの終了時に反応塊が達した温度は277℃である。次に、ポリマーのロッド状の押出を可能にするために、反応器を0.4〜0.5MPaの窒素圧力下に置き、これらのロッドを水で冷却して、切断することにより顆粒を取得する。
顆粒への湿式含浸試験は全て、加熱又は冷却可能なジャケット、プロシェアタイプの撹拌ロータ及び液体噴射装置を備えるMAP(WAMGROUP)製のMLH12L横型ミキサーを用いて実施する。使用する噴射ノズルは、流量0.1L/分及び圧力0.3MPaで噴霧角50°のTeejetノズルである。
4.1−比較例:
1’:水溶液の全重量/ポリアミドの重量=2%
2’:水溶液の全重量/ポリアミドの重量=3%
1:水溶液の全重量/ポリアミドの重量=1%
2:水溶液の全重量/ポリアミドの重量=1%
5.1.顆粒
添加済顆粒に対し実施した試験及び測定についての説明
ICPによる銅及びカリウムのアッセイ
0.5gのポリアミド顆粒を5mlの硝酸と一緒にパールボンブ(Parr bomb)中に導入する。ポリアミドの鉱化を電子レンジで行う。鉱化が終わったら、材料を水と一緒に回収してから、水を用いて用意した50mlフラスコ中に移した。銅及びカリウムを、10容量%のHNO3媒質での外部校正を用いたICP/OESによりアッセイする。
0.5gのポリアミド顆粒、2gの0.06M亜硫酸ナトリウム及び6gの浸透水を正確に計量してから、50mlのギ酸を90重量%で添加する。混合物を約1時間の撹拌により溶解させる。ポリアミドを溶解させたら、8gの水を添加する。0.02M硝酸銀(AgNO3)溶液を用いて、ヨウ素及び臭素の電位差測定アッセイを実施する。
顆粒の表面状態の分析のために、2つの顆粒を炭素ペレットに結合させた後、白金で鉱化させる。顆粒の内部を観察するため、2つの顆粒を(取り扱いやすくするため)Araldite(登録商標)エポキシ樹脂中に閉じ込め、次に、ナイフで平らに切断する。これらの切片を炭素ペレットに結合させた後、白金で鉱化させる。EDX分析と共に、15kVの走査型電子顕微鏡(SEM)で様々な調製物を観察する。
0.8gのポリアミド顆粒を20mlのトリフルオロエタノール/クロロホルム混合物(重量比10/3)に添加する。この混合物を約1時間の撹拌により溶解させる。次に、溶液をクォーツ製キュベットに移し、600〜240nmのスペクトルの補足のために分光計内に配置する。約285〜330nmのピークについてUVインデックスを計算する。
顆粒の重量に対し2%の水溶液で実施した顆粒含浸試験の結果(実施例1’)は、目標に対して添加剤の若干の不足と、均質性の不足を示している。さらに、顆粒同士及びミキサー壁への若干の凝集も見られ、これによって、取り扱いにくくなる。
実施した後処理の記述
固相後縮合
ポリマーの数平均分子量を十分に増大させるために、固相後縮合ステップを、各々4.7kgの後期添加ポリマーのバッチに対して実施する。この固相後縮合ステップは、50L回転蒸発器中で行う。顆粒を、500L/時の窒素下で195℃まで270分かけて加熱する。
縮合後のポリマーを紡糸した後、940/136糸を取得するように、工業用糸用の標準的条件下で引抜を実施する。
強制換気の下で、165℃のオーブン内で、糸に熱老化を168時間にわたり被らせる。老化前後の糸のサンプルを標準的引張試験機械での機械的試験に付すことにより、老化後の靱性、破断応力及び破断伸びの低下を決定する。あご(jaw)同士の距離200mm及びプレテンション300gで、速度500mm/分にて試験を実施する。粘度指数の減少率(%)も測定するが、粘度指数は、90%ギ酸中の0.5%溶液として測定する。測定したパラメータの減少率(%)の結果を以下の表6に記載する。
本発明の方法に従い添加した顆粒は、固相後縮合中の重合時に安定化させた参照標準と同様に挙動し、異なる熱劣化を全く呈示しない。固相後縮合後に熱安定剤の喪失は全く認められない。
