Polymer-modified automatic transmission fluid |
摘要 |
Compounded automatic transmission fluids having improved properties, including shear and viscosity properties, are obtained by the incorporation therein of alpha-olefin polymers of controlled molecular size and narrow molecular weight distribution. A shear stable, automatic transmission fluid having excellent high and low temperature viscosity properties and improved pour point is produced by adding the copolymer of 1-hexene and 1-octadecene to a lubricating oil.
