Kinetic Friction Coefficient of Polydimethylsiloxane
The Journal of the Society of Chemical Industry, Japan, 1958 末端基がトリメチルシロキシ基であるポリジメチルシロキサン[I]〓(n:1～4)および末端基にエトキシ基を有するポリジメチルシロキサン[II]〓(n:2～5)について,鋼-鋼間の動摩擦係数を振子型油性試験機によって2 5 ℃ で測定した。いずれのポリジメチルシロキサンにおいても, Si原子数が増加するにしたがって動摩擦係数が減少する。ポリジメチルシロキサン[I] の系統では, 動摩擦係数と25℃ の粘度( 対数)との関係は粘度で2～3cs,Si原子数で5～6のところを境に異なる。この結果,Si原子数5以下のポリジメチルシロキサンでは,Si-O結合のイオン性による吸着,および分子間力が動摩擦係数に大きな影響を与えているものと考えた。[II]の動摩擦係数が[I]より小さいのは ...
