Abstract
Description
本発明は、内部乳化基を有するLFプレポリマー及びそれから製造されたポリウレタン分散物に関する。本発明は、それらの分散物を製造する方法にも関する。本発明の分散物は、どのようなLFプレポリマーでもその変性によって製造することができ、そのプレポリマーの方は、脂肪族又は芳香族イソシアネート及びそれらの混合物と、ポリエーテルポリオール、ポリエステルポリオール、ポリカーボネートポリオール、ポリカプロラクトンポリオール、アクリルポリオール、ヒドロキシル末端不飽和及び水素化ポリブタジエン等、及びそれらの混合物のようなポリオールとから製造される。
例1
内部乳化性部分を有するLFプレポリマーの製造
A) 撹拌器及び温度調節器を具えたガラス反応器中へ、698.5gのアジプレン(Adiprene)LFM300〔クロンプトン社(Crompton Corporation)から得られる、遊離MDI含有量が少なく、平均分子量2760の、MDI/ポリエーテル付加物に基づくプレポリマー、初期NCO%は約3.1〕を入れた。温度を65〜70℃へもっていった。75gの1−メチル−2−ピロリジノン(NMP)中に15.5gのDMPAを入れた溶液を、LFプレポリマーへ添加した。混合物を窒素雰囲気中で約75〜80℃で約1.5時間反応させ、NCO含有量を、1.46%の理論的計算値に到達させた。得られたプレポリマーは、懸垂カルボキシル基を含んでいた。
低遊離MDIプレポリマーに基づく陰イオン性ポリウレタン分散物の製造
約0.001%の結晶質オルト燐酸、反応遅延剤を例1Aのプレポリマーへ添加し、混合物を85℃へ加熱して粘度を低くした。688.3gの量の熱いプレポリマーを、28.8gの外部表面活性剤T−DET−N14〔ハークロス・ケミカル社(Harcross Chemical Inc.)からのもの〕及び10.5gのトリエチルアミン(TEA)を含有する15〜20℃の冷水1260g中に分散させた。プレポリマーが完全に分散した後、それを10.5gの35%ヒドラジン水溶液で鎖伸長した。これは、32.8%の固体含有量、及び30cpsの粘度(ブルックフィールドLVF、スピンドル#2、60rpm、25℃)を有する安定なミルク状ポリウレタン分散物になった。このポリウレタン分散物をガラス表面上に注型し、イオン性沈澱によりポリウレタンフイルムを形成した。フイルムの性質は、医療用装置、被覆、及び接着剤のような用途に対し優れていることが明らかであった。
医療用途で例2の分散物の有用性を例示するため、100%ポリウレタンの手袋を、次の慣用的技術を用いて、イオン性沈澱により製造した。
低遊離MDIプレポリマーに基づく非イオン性ポリウレタン分散物の製造
例1Bのプレポリマー(469g)を、11〜13℃の冷水832g中に分散した。プレポリマーが完全に分散した後、分散物を6.4gの35%ヒドラジン水溶液で鎖伸長した。これは、34.1%の固体含有量、及び130cpsの粘度(ブルックフィールドLVF、スピンドル#2、60rpm、25℃)を有する安定なポリウレタン分散物になった。
低遊離HDIプレポリマーに基づく陰イオン性ポリウレタン分散物の製造
例1Dのプレポリマー(440g)を反応器中へ入れ、80℃に加熱し、次に5.4gの外部表面活性剤T−DET−N14及び9.5gのTEAを含有する11〜13℃の冷水750g中に分散した。プレポリマーが完全に分散した後、そのプレポリマーを9.0gの35%ヒドラジン水溶液で鎖伸長した。これは、31.8%の固体含有量、及び430cpsの粘度(ブルックフィールドLVF、スピンドル#2、60rpm、25℃)を有する安定なポリウレタン分散物になった。そのポリウレタン分散物をガラス表面上に注型し、数時間空気乾燥することによりポリウレタンフイルムを形成し、然る後、それらを120℃で20分間アニールした。フイルムの機械的性質は、次の通りであった:100%モジュラスは910psiであった;500%モジュラスは2800psiであった;抗張力は5000psiであった;破断時伸びは650%であった。
低遊離MDIプレポリマーに基づく陰イオン性ポリウレタン分散物の、有機共溶媒を用いない製造
頂部撹拌器及び温度調節器を具えたガラス反応器中へ、446.7gのLFM X−1300を入れた。温度を45〜50℃へ持って行き、53.3gのCAPA587047、カルボキシル官能性ポリオールを添加した。混合物を窒素雰囲気中で約45〜50℃で約3時間反応させ、NCO含有量を、1.37%の理論的計算値に到達させた。そのプレポリマーを、19.6gの外部表面活性剤T−DET−N14及び7.49gのTEAを含有する11〜13℃の冷水930g中に分散した。プレポリマーが完全に分散した後、その分散物を6.4gの35%ヒドラジン水溶液で鎖伸長した。これは、33.1%の固体含有量、及び70cpsの粘度(ブルックフィールドLVF、スピンドル#2、60rpm、25℃)を有する安定なポリウレタン分散物になった。そのポリウレタン分散物をガラス表面上に注型し、数時間室温で乾燥し、120℃の炉中で20分間アニールすることによりポリウレタンフイルムを形成した。フイルムの機械的性質は、次の通りであった:100%モジュラスは220psiであった;500%モジュラスは1850psiであった;抗張力は4300psiであった;破断時伸びは650%であった。
MDI及びポリエステルポリオールからの陰イオン性ポリウレタン分散物の製造
頂部撹拌器及び温度調節器を具えたガラス反応器中へ、393.3gのFOMREZ22−56(クロンプトン社から得られるMW2000のポリエチレングリコールアジペート)を入れ、それを次に65℃へ加熱した。第二工程として、96.07gのMDIを添加し、温度を75℃へ上昇させた。1時間後、NCO%が3.2として測定された。反応を50℃へ冷却し、45gの1−メチル−2−ピロリドン(NMP)中に10.65gのDMPAを入れた溶液をプレポリマーへ添加した。混合物を窒素雰囲気中約45〜50℃へ約3時間反応させた。最終的NCO%は1.19であり、それは理論的計算値(1.21%)に近い。この段階でプレポリマーの粘度は余りにも高く、18.4gの外部表面活性剤T−DET−N14及び7.3gのTEAを含有する11〜13℃の冷水840g中に分散するのを困難にしていた。プレポリマーを水に完全に添加した後、分散物を8.02gの35%ヒドラジン水溶液で鎖伸長した。得られた分散物は多量のグリットを含み、濾過するのが不可能であった。ガラス板上で注型した時、その分散物は均一なフイルムを形成しなかった。明らかにこの例は、例2の変性LFプレポリマーから分散物を形成し易いのに比較して、慣用的MDIプレポリマーから有用な分散物を形成するのは困難であることを例示している。
MDI及びポリエステルポリオールからの非陰イオン性ポリウレタン分散物の製造
頂部撹拌器及び温度制御器を具えたガラス反応器中へ、393.3gのFOMREZ22−56を入れ、次にそれを65℃へ加熱した。第二段階で96.07gのMDIを添加し、温度を75℃へ上昇させた。1時間後、NCO含有量は3.2%として測定された。反応を50℃へ冷却し、118gのメトキシカルボワックス(MPEG−750)を添加した。混合物を、窒素雰囲気中約80℃で約3時間反応させ、NCO含有量を計算値(1.12%)へ到達させた。得られたプレポリマーを分散させる試みは失敗した。プレポリマーは、それを伸長できるようになる前に、水中でゲルを形成した。この例も、例4の変性LFプレポリマーと比較して、慣用的MDIプレポリマーから分散物を形成するのは困難であることを例示している。
慣用的HDIプレポリマーからの陰イオン性プレポリマー分散物の製造
撹拌器及び温度調節器を具えたガラス反応器中へ、279.4gのFOMREZ66−112を入れ、次にそれを45℃へ加熱した。次に、102.6gのHDIを添加し、温度を100℃へ上昇させ、然る後、それを95℃へ冷却し、この温度に1時間保持した。反応のこの段階で、試料をNCO含有量%について分析した。それは6.5%であることが判明した。反応を70℃へ冷却し、197gのM−ピロール溶媒中に18.5gのDMPAを入れたものを添加した。混合物を約80℃で窒素雰囲気中で更に1.5時間反応させ、ここでNCO含有量は理論的2.35%に到達した。得られたプレポリマーを、12.4gの外部表面活性剤T−DET−N14及び13.1gのトリエチルアミンを含む冷水(11〜13℃)1050g中に分散した。プレポリマーを分散した後、それを、12.5gの35%ヒドラジン水溶液で鎖伸長した。得られた分散物は極めてグリット状であり、50℃の炉中で5日後にゲル化した。この例と例5とを比較すると、分散物を作る場合の変性LFプレポリマーの利点が分かる。
