トルエン中のメチルホスホン酸(6.4g、Aldrich)およびポリジメチルシロキサン(Mn 550、48.7g、Gelest)の混合物を150℃で24時間撹拌した。トルエンを除去して、粘性のある改質シリコーン樹脂(i)を得た。
フェニルホスホン酸ジクロリド(7.0g、Aldrich)を26.3gのポリジメチルシロキサン(Mn 550、Gelest)に加え、混合物を室温で真空下、一晩撹拌した。混合物は粘性を帯び、エラストマー配合物に使用できる状態であった。
フェニルホスホン酸(28.5g、Aldrich)およびポリジメチルシロキサン(Mn 550、116.6g、Gelest)の混合物を、撹拌装置、Dean−Starkトラップおよび冷却器を備えた500mlの丸底フラスコ内のトルエンに溶解させた。フラスコを70℃で15時間加熱し、続いて、110℃で3時間加熱した。次いで、混合物を150℃まで昇温し、水(6.5ml)を回収した。トルエンを真空により除去し、粘性のある改質シリコーン樹脂(ii)生成物を回収した。
メチルホスホン酸(2.0g、Aldrich)、1,3−ジクロロ−1,1,3,3−テトラメチルジシロキサン(2.57g、Aldrich)および1,7−ジクロロ−オクタメチルテトラシロキサン(4.53g、Aldrich)の混合物を80℃で24時間撹拌した。この溶液に、シラノール末端ジフェニルシロキサン−ジメチルシロキサンコポリマー(4.6ml、Gelest)を加えた。混合物を100℃で68時間加熱し、〜1500cPの粘度を有する樹脂を生成した。
本明細書に開示されるエラストマー配合物は、式(I)および/または(II)の構造を有する少なくとも1つの改質シリコーン樹脂、少なくとも1つのタイプの金属酸化物、任意選択で、少なくとも1つのシリケート(例えば、エチルシリケート)、任意選択で、少なくとも1つのシリカおよび少なくとも1つの硬化剤を含むことができる。改質シリコーン樹脂は、約10重量パーセントから約95重量パーセントのエラストマー配合物とすることができる。エラストマー配合物の金属酸化物は、約1ナノメートルから約5マイクロメートルの範囲の粒径(直径)を有する酸化物微粒子を含む。エラストマー配合物は、配合物中に約2重量パーセントから約80重量パーセントの金属酸化物を含むことができる。エラストマー配合物には、酸化鉄(例えば、FeO、Fe2O3およびFe3O4)、酸化チタン(例えば、TiO2)、酸化セリウム(例えば、CeO2)、酸化亜鉛(例えば、ZnO)および酸化ジルコニウム(例えば、ZrO2)またはこれらの酸化物の混合物を使用してもよい。エチルシリケートは、エラストマー配合物中に約0重量パーセントから約25重量パーセント存在することができる。シリカは、エラストマー配合物中に約0重量パーセントから約10重量パーセント存在することができる。硬化剤は、エラストマー配合物中に約0.1重量パーセントから約10重量パーセント存在することができる。適した硬化剤には、例えば、有機金属触媒(例えば、ジブチルチンジラウラート、トリス(ジメチルアミノ)メチルシランおよびエチルトリアセトキシシラン、ならびに、とりわけ、その組み合わせ)が含まれ、これらは、当技術分野において縮合反応の促進に周知のものである。上述の成分の開示された重量パーセントは、ニートの配合物については、成分の総量が合計で100重量パーセントになるものである。
