上記ポリオレフィンには、各種オレフィンの重合物、又はこれらの水素化物が含まれる。オレフィンとしては任意のものが用いられるが、例えば、エチレン、プロピレン、ブテン、炭素数5以上のα−オレフィンなどが挙げられる。ポリオレフィンの製造にあたっては、上記オレフィンの1種を単独で用いてもよく、2種以上を組み合わせて用いてもよい。特にポリα−オレフィン(PAO)と呼ばれているポリオレフィンが好適であり、これはグループ4の属する基油である。これら合成基油の粘度は特に制限されないが、40℃における動粘度は、好ましくは2〜680mm2/s、より好ましくは8〜220mm2/sである。
天然ガスの液体燃料化技術のフィッシャートロプッシュ法により合成されたGTL(ガストゥリキッド)は、原油から精製された鉱油基油と比較して、硫黄分や芳香族分が極めて低く、パラフィン構成比率が極めて高いため、酸化安定性に優れ、蒸発損失も非常に小さいことから、本発明の基油として好適に用いることができ、これはグループ3基油である。GTL基油の粘度性状は特に制限されないが、通例、粘度指数は130〜180、より好ましくは140〜175である。また40℃における動粘度は、2〜680mm2/s、より好ましくは5〜120mm2/sである。また、通例、全硫黄分は10ppm未満、全窒素分1ppm未満である。そのようなGTL基油商品の一例として、SHELL XHVI(登録商標)がある。
これらの追加的な添加剤は、その全配合量を組成物全量基準で、通常、約0.05〜25重量%程度の範囲にすることが好ましい。
その粘度指数向上剤としては、例えば日本国特許第954077号、第1031507号、第1468752号、第1764494号、第1751082号等に記載されているスチレン−ブタジエン共重合体、スチレンーイソプレン星状共重合体、ポリメタクリレート系、エチレン−プロピレン共重合体などが挙げられ、これらは1から20質量%の割合で使用される。またこれらのものに窒素原子や酸素原子を分子中に含んだ極性モノマーを共重合させた分散型粘度指数向上剤についても同じように使用することができ、一般には、ポリメタクリレ−ト、エチレン−プロピレン共重合体やスチレン−ブタジエン共重合体などのオレフィン共重合体、ポリブテンなど、あるいはこれらに分散性を付与した分散型のものを使用する。
特にポリメタクリレ−トが好ましく、用いられるポリメタクリレ−トの分子量は1万〜200万であり、特に好ましくは10万〜50万のものである。ポリメタクリレ−ト等粘度指数向上剤は組成物中に通常0.5〜20重量%,好ましくは1〜10重量%配合される。
上記ポリジメチルシロキサンは、25℃における動粘度が約10,000〜60,000mm2/s程度が好ましい。もちろん上記粘度以下のポリジメチルシロキサンを含むことが排除されるものではないが,含有量が多くなると潤滑油が濁ったり、あるいは潤滑油中に分散することができず沈降したりするために、そうしたことが起こらないような適当な含有量に留めることが必要である。このポリジメチルシロキサンは、単独で、あるいは粘度の異なった二種以上のものを組み合わせて使用することができる。その使用量については、基油に、Si換算で、組成物全量を基準として、約0.1〜30ppm(重量ppm:以下同じ)の割合で配合される。0.1ppm未満では消泡性の効果がでない場合があり、30ppmを超えると潤滑油組成物が濁ったり、逆に消泡効果がでない場合がある。より好ましくは、約3〜10ppmの範囲である。

アルゴン雰囲気下において、還流管を付けた300mlの三口フラスコにヘキサメチルジシラザン(2.64g,16.4mmol)を加え、トルエン50mlに溶かした。続いて、フラスコを50℃に加熱しながら、滴下漏斗を用いてクロロジイソプロピルホスフィン(5.00g,32.8mmol)のトルエン溶液100mlを30分かけて滴下し、さらに3時間攪拌した。
室温に冷却し、単体硫黄(1.05g,4.10mmol)を加え、さらに7時間加熱還流を行った後に0℃において1日放置した。得られた白色の結晶を二硫化炭素およびn−ヘキサンで洗浄した後にジクロロメタンとn−ヘキサンからの再結晶を行い、精製した。
