Title (EN) LUBRICANT AND MAGNETIC DISK
(FR) LUBRIFIANT ET DISQUE MAGNÉTIQUE
(JA) 潤滑剤及び磁気ディスク
Abstract: front page image
(EN)Disclosed is a lubricant containing a compound represented by formula (1). In the formula, n is substantially 2, 3, or 4 and R is a C1–4 fluoroalkyl group. Rf is –CF2O(CF2CF2O)x(CF2O)yCF2– or –CF2CF2O(CF2CF2CF2O)zCF2CF2–. x, y, and z are each zero or a positive real number such that the number average molecular weight of the fluoropolyether represented by HOCH2–Rf–CH2OH and containing aforementioned Rf is 500 to 2000. The molecular weight distribution of said fluoropolyether (PD, weight average molecular weight/number average molecular weight) is 1.0 to 1.5.
(FR)L'invention porte sur un lubrifiant contenant un composé représenté par la formule (1). Dans la formule, n représente essentiellement 2, 3 ou 4 et R représente un groupe fluoroalkyle en C1–4; Rf représente –CF2O(CF2CF2O)x(CF2O)yCF2– ou –CF2CF2O(CF2CF2CF2O)zCF2CF2–; x, y et z représentent chacun zéro ou un nombre réel positif tel que la masse moléculaire moyenne en nombre du polyéther fluoré représenté par HOCH2–Rf–CH2OH et contenant Rf susmentionné est de 500 à 2000. La distribution de la masse moléculaire dudit polyéther fluoré (PD, masse moléculaire moyenne en poids/masse moléculaire moyenne en nombre) est de 1,0 à 1,5.
(JA) 式(I)で表される化合物を含有する潤滑剤 式中nは実質的に2、3または4であり、RはC1~4のフルオロアルキル基である。Rfは-CFO(CFCFO)(CFO)CF-又は-CFCFO(CFCFCFO)CFCF-である。x、y、zはそれぞれ、上記Rfを含むHOCH-Rf-CHOHで示されるフルオロポリエーテルの数平均分子量が500~2000となる0または正の実数であり、該フルオロポリエーテルの分子量分布(PD、重量平均分子量/数平均分子量)は1.0~1.5である。
