Abstract
Description
(I) R1-アリール-(-(CH2)n-NH2)a
〔式中、R1=H、C1〜C6アルキル、特にH
a=2または3
n=1〜4〕。
特に、アミノアルキル置換フェニル化合物またはアミノアルキル置換ナフチル化合物が適当であり、特に2置換化合物が適当である。例えば、ジ(アミノメチル)ナフタレンおよびキシリレンジアミン(XDA)、特にmXDAが、更なる反応のためのアミン化合物として適当である。
実施例:
354g(2.6mol)のメタ-キシリレンジアミン(mXDA)をフラスコ中に入れ、攪拌した。T=50〜70℃において約1時間にわたってエチルアクリレート(137.6g、1.375mol)をゆっくりと添加した(比率(モル):mXDA/Et-Acr=1:0.53)。温度を70℃において15分間保った。その混合物を140℃で保ち、生成したエタノールを留去した。次に、3.25時間、Tを170〜190℃に上げ、その後室温に冷却した。エタノール(375g)を溶媒として添加した。ビスフェノールAジグリシジルエーテル(84.8g、0.25mol)および1,4-ブタンジオールジグリシジルエーテル(46.4g、0.23mol)を10分間にわたって添加した。温度を70℃において1時間保ち、その後冷却した。表1に従って、エタノールを用いて反応混合物を希釈した。その数平均分子量MNは604であった(GPC)。
0.38molのmXDAおよび0.19molのエタノールアミンを、攪拌しながらフラスコ中で混合し、60℃の温度に加熱した。0.35molのエチルアクリレートを80分間にわたって添加した。反応温度を135℃に上げ、そこで1時間保った。そうして生成したエタノールを5〜6時間にわたって留去し、ここで、理論量の約90%が測定されるまで温度を170℃に上げた。次に、混合物をRTまで冷却した。ビスフェノールAジグリシジルエーテル(0.08mol)を約30分間にわたって添加した。温度を70℃にし、そこで1時間保った。生成物をRTまで冷却した。場合により、粘度を調整するために多少のエタノールを添加してよい。
実施例2と同様の手順をたどったが、ビスフェノールAジグリシジルエーテルに代えて、それぞれ0.08molのビスフェノールAジグリシジルエーテルおよびブチレングリコール-1,4-ジグリシジルエーテルの混合物を用いた。
次の量を用いて、実施例2による方法を繰り返した:エタノールアミン:0.17mol;mXDA:0.35mol;エチルアクリレート:0.39mol;ビスフェノールAジグリシジルエーテル:0.09mol。
実施例1と同様に、0.5molのエチルアクリレートおよび1.0molのmXDAを反応させた。エタノールの留去およびRTへの冷却後、145gのエタノール(溶媒として)を添加した。4.5molのブチレングリコール1,4-ジグリシジルエーテルを10分間にわたって添加した。70℃の温度を30分間にわたって維持した。5.0molのJeffamine T-403を3分内に添加し、2時間攪拌を行った。その後、この混合物を50℃において1時間保った。
実施例1に記載されるように製造を行ったが、ポリエポキシドを用いず、次の量を用いた:
ブタンジオールジグリシジルエーテル(硬化剤1)またはテトラグリシジル-mXDA(硬化剤2)を成分Aとして用いた。塗布後、昇温(40〜70℃)における乾燥トンネル中で基材が接着する前の空気循環を用いて、溶媒を除去した。
比較実施例のアミノ化合物をエタノール中に溶解させ(60重量%の固体含有量)、硬化剤2と混合した(1:0.313)。この混合物を、PTFEで製造された鋳型(面積:100mm×100mm)中に注ぎ、乾燥および硬化後に1mm厚のフィルムを形成させた。更なるフィルムを、上記表から、次の実施例に基づいて製造した:
・ 実施例1 + 硬化剤1
・ 実施例1 + 硬化剤2
・ 実施例2 + 硬化剤3
・ 実施例5 + 硬化剤2
室温(24℃)において接着剤および硬化剤を口広フラスコに入れ、時間にわたる温度カーブを通じて発熱を監視した。次の組成物を調製し、テストした:
a)比較実施例のアミン成分をエタノール中に溶解させ(50重量%の固体含有量)、硬化剤1と混合した(1:0.31)。
b)実施例1のアミン成分をエタノール中に溶解させ(50重量%の固体含有量)、硬化剤1と混合した(1:0.27)。
測定方法:
数平均分子量MNをゲルパーミエーションクロマトグラフィ(GPC)によって測定した:
標準:PSS製のポリスチレン標準
カラム:PLgel 50Å、100ÅおよびUltrastyragel 500Å溶離剤、それぞれ7.8×300mmおよび5μm(Polymer Laboratories and Waters)
カラムオーブン温度:85℃
溶離剤:1g/Lのリチウムクロリドを有するN-ジメチルアセトアミド
流速:1.0mL/分
検出器:屈折率検出器;感度16、35℃
注入量:100μL
200±10mgの試料(6×測定)を25-mLのメスシリンダー中に秤量し、溶離剤を添加しながら溶解させ、次にメスシリンダーを、マークまで溶離剤でいっぱいにした。そうして調製した試料を、0.45-μmのシリンジフィルターを通して試料容器中に濾過した。分子量の決定は、PSS製の上記の狭い分布のポリスチレン標準を用いた外部較正(三次多項式)に基づく。
ストリップカッターを用いて、複合材料の15mm-幅の片を切断した。次に複合材料を、手によって、またはホットシールジョー端(hot sealing jaw edge)上に分離した。場合により、複合材料片の一端をエチルアセテート中に挿入することが有用であり得る。汎用引張試験機、強度範囲0〜20N(例えばInstronまたはZwick製)を用いて測定を行った。予め分離した複合材料片を固定し、引張試験機を100mm/分の引張速度において開始した。引張角は90°であり(手動で維持される)、引張長は5〜10cmであった(変動範囲による)。測定を3回繰り返した。これら3回の測定の平均値として化合物接着性が得られた。
MOCON製のOX-TRAN 2/21 H測定装置を用いて酸素透過性を決定した。測定機器の試験セルは、2部分からなる。フィルムを2部分セルの間に載せた。試験ガスとして酸素を、外部分セルを介して通した。95%の窒素および5%の水素の混合物(必須にガスを形成する)のキャリアガスを、内部分セルを介して流した。フィルムを通じて浸透する酸素をキャリアガスによって補足し、検出器に運んだ。酸素センサーは酸素の存在下において電流を発生し、この電流は酸素の到達量に比例する。
ブルックフィールドLVT粘度計を用いて、ISO 2555規格に従って上記の温度において粘度を決定した。スピンドルおよびせん断速度の選択は、温度および粘度範囲に依存する(例えば、RT〜30°および約1000-5000mPasの粘度において、スピンドル27およびせん断速度5rpmが適当である)。
