式中、各R3は、上記で定義されているが、ただし、少なくとも1つのR3は、ベータ-アミノアルコール部分Wに結合したシリコン結合二価連結基であり、下付き文字a、b、c、およびdは、それぞれa+b+c+d=1となるようなモル分率であるが、ただし、a+b+c>0である。
[R3 3SiO1/2]a[R3 2SiO2/2]b[R3SiO3/2]c[SiO4/2]d
式中、下付き文字a、b、c、およびd、ならびに各R3は、独立して選択され、上記で定義されているが、ただし、a+b+c>0であり、少なくとも1つのR3がエポキシド官能基を含む。特定の実施形態において、例えば、少なくとも1つのR3は、上記の二価連結基D2である。
すべての試料を、Rigaku Primus I波長分散型蛍光X線分析装置(WDXRF)分光計(「XRF装置」)を使用して分析する。
XRF装置には、一次ビームフィルターを備えた最大4kWのRhターゲットX線源、Rh K-ラインオーバーラップ(Ru、Rh、Pd、Ag、Cd、In、およびSn K-ライン)用のNi400、Rh L-ラインオーバーラップ(Ru、Rh、Pd、Ag、Cd、In、およびSn L-ライン)用のAl25、およびデリケートな試料のX線管保護用のBe30が装備されている。結晶の分析としては、LiF200(K-U)、PET(Al-Si)、Ge(P-Cl)、RX25(F-Mg)、RX35(O)、RX45(N)、RX61F(C)、およびRX75(B)が挙げられる。検出器には、Ti-U用のシンチレーションカウンター(SC)およびB-Ca用のガス(フロー)比例計数管が含まれる。
すべての試料を、Thermo Scientific Nicolet 6700フーリエ変換赤外(FTIR)分光計を使用して分析する。
すべての試料を、Agilent400MHz NMR分光計を使用して分析する。
レオロジー測定は、カップとボブセンサーを備えたTA Instruments DHR-3レオメーターを使用し、25℃で40mmのコーンとプレートを使用して行う。
調製:
1000mLの4つ口丸底フラスコには、攪拌パドルとモーター、ゴム製血清キャップ、窒素注入口、およびクライゼンアダプターが取り付けられている。クライゼンアダプターには、J-KEMコントローラに接続された地下熱電対と、鉱油バブラーに接続されたフリードリッヒコンデンサーとが取り付けられている。フラスコに、ヒドロキシル官能性多糖(56.75gのCELLOSIZE(商標)HECEP-300、Dow Chemical Company、Midland MI製;50.23gのHEC含有量、0.2009モル、DS2.0)、ハロゲン化アジリジニウム前駆体(N-メチルアミノエチルクロリド塩酸塩);31.68g、0.2437モル)、およびイソプロピルアルコール(IPA)(280.4g)と脱イオン水(32.4g)との混合物を充填して、スラリーを形成する。窒素(毎秒約1気泡)でパージしながら、スラリーを1時間撹拌(撹拌モーターを70rpmに設定)して、混入した酸素を除去する。
アミノエチル多糖類を手作業で粉砕し(乳鉢と乳棒)、スクリーニングし(#30米国標準ふるい)、上記の手順に従って分析して、次の結果が得られた。
アミノエチル多糖の調製
5つのアミノエチル多糖HCl塩(調製例2~6)は、以下の表2に記載のように、様々なハロゲン化アジリジニウム前駆体を使用して、上記の調製例1の手順に従って調製される。
アミノエチル多糖HCl塩を、還流冷却器および窒素入口を備えた3つ口フラスコ内の80:20のIPA/H2O混合物(200g)に懸濁する。混合物を窒素ガスで1時間フラッシュする。次いで、NaOH溶液(水中50重量%;Kjeldahl窒素値に基づいて1当量)を一度に加える。溶液混合物を加熱して、70℃で4時間保持し、次いで自然冷却させる。反応混合物を室温で18時間激しく撹拌している。
調製:
アミノエチル多糖(中和された)を、マグネチックスターラーを備えた20mLのシンチレーションバイアルで秤量した。シロキサン重合度(DP)(すなわち、分子あたりのケイ素中心の数)を有するエポキシド官能性有機ケイ素化合物を一度に添加し、反応混合物を多成分希釈剤(IPA/H2O)に懸濁させるバイアルを70℃の加熱ブロック内に置き、反応時間(T)の間攪拌する。反応混合物を自然に室温に冷却し、アセトン(10mL)を充填して、シリコングリカンを含む反応生成物を得る。
シリコンの取り込みはNMRで確認し、シリコングリカンを上記の手順に従ってATR-IRおよびXRFで分析する。
