Abstract

Copoliéteres de bloque que tienen la fórmula (I): RX-(CH2-CHR1-O-)x-(-CH2CHR2-O-)y-(-CH2-CHR3-O-)z-R4donde: R está seleccionado de H,alquilo, alquilarilo; X está seleccionado de O, S y N; R1, R2 y R3 están seleccionados deH , CH3 y radicales alquilo C2-C10; R4está seleccionado de H,alquilo,acilo;x,y,z todos diferentes de cero,representan el número de unidades éter de cada bloque, son enteros que tienen valores talesque el peso molecular del compuesto que tiene lafórmul a descripta está entre 600 y 4000, preferiblemente entre 800 y 2000, y además (x+z)/yestá entre 1,5 y 5,0; con la condición que: a) bien R1 y R3 son seleccionados entre H y CH3, en cuyo caso R2 está seleccionado entre radicalesalquilo C1 aC10, b) o R1 y R3 están seleccionados de radicales alquilo C2-C10, en cuyo caso R2 está seleccionado de H y CH3. El compuesto puede ser utilizado como unun aceite lubricante para engranajes industriales, mecanismos diferenciales yaceite par a motor de dos ciclos. También puede ser utilizado como componentede formulaciones de aceites lubricante parcial y totalmente sintético para motores de 4 ciclos.
