  • Copolymer useful as a pour point depressant for a lubricating oil
    Patent number: 5368761
    Abstract: A copolymer useful as a pour point depressant for hydrocarbon lubricating oils includes from about 15 mole percent to about 67 mole percent comonomeric units derived from a (C.sub.8 -C.sub.15) alkyl (meth)acrylate monomer, from about 3 mole percent to about 40 mole percent comonomeric units derived from a (C.sub.16 -C.sub.24) alkyl (meth)acrylate monomers and from greater than 30 mole percent to about 65 mole percent comonomeric units derived from a (C.sub.1 -C.sub.4)alkyl (meth)acrylate monomer.
