振動ひずみ振幅掃引試験方法
振動ひずみ振幅掃引試験は、手動モードでAnton Parr MCR301レオメーターを使用して実行する。貯蔵弾性率(G’)および損失弾性率(G’’)は、試料を2つのレオメータープレートの間に置き、ひずみを増やすことによって測定する。測定は、約0.4mgの試料サイズを有する、直径50mm、コーン角1°のコーンとプレートジオメトリを使用して室温で行う。Rheoplusソフトウェア3.41を使用して、機器を較正し、実験を設定および実行し、生の実験データを収集および分析する。
poly-THFは、Mnが2900のビス-ヒドロキシ末端ポリテトラヒドロフランである。これは、疎水性コモノマーであり、Sigma Aldrich(Millipore Sigma)からポリテトラヒドロフランとして市販されている。
AROMATIC200は、最初に分子ふるいを使用して少なくとも12時間乾燥させ、乾燥した溶媒を使用して、12重量%のポリTHF溶液を調製する。AROMATIC200中のポリTHF溶液は、使用前に分子ふるいを使用して少なくとも12時間再度乾燥させる。反応で使用されるすべてのガラス製品およびジョイントは、150℃のオーブンで乾燥させる。ステップ1で、150mLの12重量%ポリ-THF溶液、イソホロンジイソシアネート(1つのヒドロキシ基あたり2当量のNCO)、およびSn触媒(50mg)を、3口フラスコである反応器に装填する。オーバーヘッド撹拌しながら反応器を90℃に加熱する。反応混合物を90℃で1時間保持する。40℃まで冷却する。0.9当量(未反応のNCOに基づく)の1,2-ジアミノプロパン(DAP)を添加し、反応混合物を40℃で30分間保持する。次に、0.1当量のブチルアミンを添加し、得られた混合物を70℃まで加熱し、すぐに40℃まで冷却する。生成物混合物のMnを、較正標準を使用してゲル浸透クロマトグラフィー(GPC)により分析する。ポリマー特性を以下の表1に示す。
実施例1Aを繰り返すが、NCO末端プレポリマーは、ステップ2で0.2当量の1,2-ジアミノプロパンと反応させる。ポリマー特性を表1に示す。
実施例1の手順を繰り返すが、ステップ1でイソホロンジイソシアネート(IPDI)の代わりにヘキサメチレンジイソシアネートを使用する。ポリマー特性を以下の表1に示す。
poly-THF溶液を実施例1のように調製する。ステップ1で、150mLの12重量%のポリ-THF溶液、イソホロンジイソシアネート(1つのヒドロキシ基あたり1.05当量のNCO)、およびSn触媒(50mg)を、3つ口フラスコである反応器に装填する。オーバーヘッド撹拌しながら反応器を90℃まで加熱する。反応混合物を90℃で1時間保持する。0.95当量のイソホロンジイソシアネートを添加し、90℃でさらに1時間保持する。40℃まで冷却する。0.9当量(未反応のNCOに基づく)の1,2-ジアミノプロパンを添加し、反応混合物を40℃で30分間保持する。次に、0.1当量のブチルアミンを添加し、得られた混合物を70℃まで加熱し、すぐに40℃まで冷却する。生成物混合物のMnは、較正標準を使用してGPCにより判定する。
MSOは、分子ふるいを使用して少なくとも12時間乾燥させる。反応に使用されるすべてのガラス製品およびジョイントは、150℃のオーブンで乾燥させる。以下は、MSO中のポリ-THF、ジイソシアネート、およびジアミンを含む重縮合反応の一般的な手順である。30gのポリ-THFを装填し、反応器を70℃まで加熱して、オーバーヘッドミキサーを使用して撹拌され得るポリ-THF溶融物を調製する。イソシアネート(1つのヒドロキシル基あたり2当量)およびSn触媒(50mg)を70℃で反応器に装填する。反応混合物を70℃で1時間保持する。300mlのMSOを混合物に添加し、混合物は、ポリウレタンプレポリマーを含む。40℃まで冷却し、残留NCOに基づく0.9当量の1,2ジアミノプロパンを添加し、反応混合物を40℃で30分間保持する。次に、ブチルアミンを40℃で添加し、混合物を70℃まで加熱し、すぐに40℃まで冷却する。生成物混合物のMnは、較正標準を使用してGPCにより判定する。
以下は、溶媒を使用しないポリ-THF、ジイソシアネート、およびジアミンを含む重縮合反応の一般的な手順である。反応に使用されるすべてのガラス製品およびジョイントは、150℃のオーブンで乾燥する。30gのポリ-THFを装填し、反応器を90℃まで加熱して、オーバーヘッドミキサーを使用して撹拌され得るポリ-THF溶融物を調製する。イソシアネート(1つのヒドロキシル基あたり2当量)およびSn触媒(50mg)を90℃で反応器に装填する。反応混合物を90℃で1時間保持する。90℃で残留NCOに基づく0.9当量の1,2ジアミノプロパンを添加し、反応混合物を90℃で30分間保持する。次に、0.1当量のブチルアミンを90℃で添加し、さらに30分間保持する。生成物混合物のMnは、較正標準を使用してGPCにより分析する。
最初のスクリーニングでは、低剪断ブルックフィールド粘度を使用して、実施例1のポリ尿素系ポリマーレオロジー調整剤がAROMATIC200を濃縮する能力を研究する。表1に示されるように、AROMATIC200のベースライン粘度は、17cPである。12重量%のプレポリマー濃度で、粘度は、78cPに増加する。0.2当量の1,2-ジアミノプロパン(DAP)(実施例1B)と共に尿素を官能的に導入すると、粘度は、さらに180cPに向上し、Aromatic200中の疎水性ポリ尿素の濃縮効果に対する尿素基の影響を示す。実施例1Aのレオロジー調整剤を使用すると、劇的に、かつ望ましく粘度が増加し、12重量%で撹拌することができないゲルの形成を引き起こす。AROMATIC200中で6.6重量%に希釈した後でも、実施例1Aのレオロジー調整剤の分散物の粘度は、12,8312cPと高いままである。3重量%に希釈すると、粘度は、3,356cPと高いままである。これは、ポリマーチェーン内の尿素濃度の影響、およびある程度、ポリマーレオロジー調整剤のMnが、AROMATIC200中の実施例1Aのポリマーの会合挙動に対する影響を実証する。
加えられたひずみの関数としての、Aromatic200中の実施例1A(Mn=約19.2k)のゲルのポリマーの貯蔵および損失弾性率は、上記の方法に従って測定する。結果は、6重量%のポリマーについて図1に示し、10重量%のポリマーについて図2に示す。6重量%のポリマーでは、実施例1Aのレオロジー調整剤を使用して調製された油製剤は、明確な貯蔵弾性率を示し、ひずみ振幅の増加に伴って変化しない。これは、ポリマーレオロジー調整剤が驚くべきことに、Aromatic200中で安定したゲルネットワークを形成することを実証する。粘土またはシリカ系レオロジー調整剤で配合された油の貯蔵弾性率は、より高いひずみ振幅で減少する傾向があることは、当業者に知られている。
実施例1Aのポリマーレオロジー調整剤と、所定の油中の望ましい濃度のドデシルスルホン酸カルシウムとの均一な溶液を、適量の実施例1Aの原液(Aromatic200中のポリマーの12重量%溶液)と、適量のドデシルスルホン酸カルシウム(Solvesso150中で30重量%)とを混合することによって調製し、70℃まで加熱する。得られた分散物を、オーバーヘッドスターラーを使用してよく混合し、室温まで冷却する。油中のポリマー溶液は、使用前に24時間平衡化する。
