PURPOSE:To obtain the title composition having excellent compatibility with HCFC, wear resistance and lubricating performances by blending a polyoxyalkylene glycol derivative with a specific chlorinated aryl phosphate. CONSTITUTION:(A) A polyoxyalkylene glycol derivative preferably shown by formula l and/or formula II (R<1>, R<3>, R<5>, R<7> and R<9> are H, 1-20C alkyl, etc.; R<2>, R<4>, R<5> and R<8> are 2-4C alkylene; m is 3-100; n, p and r are positive integer to satisfy 3<=n+p+r<=100) is blended with (B) preferably 0.1-10wt.% chlorinated aryl phosphate shown by formula III (R is H or 1-12C alkyl; x and y are 1-3 integer and x+y is <=5) to give the objective composition. |
