  • Process for the preparation of multifunctional additive for aqueous lubricants
    Patent number: 8969268
    Abstract: The present invention deals with a process for the preparation of multifunctional additive for aqueous lubricants. These I multifunctional additive for aqueous lubricant comprises of co-polymer having vinyl group containing polyhydric alcohol along with monomer selected from aqueous soluble acrylate co-monomer in different mole fraction for addition polymerization to facilitate the sequencing of monomer in polymer chain. Thus the polymeric molecule has been designed for improving tribological properties i.e. low wear, low friction and EP property of aqueous lubricants.
