  • Ethylene based copolymer compositions as viscosity modifiers and methods for making them
    Patent number: 8999907
    Abstract: Polymeric compositions and methods for making and using the same are provided. The polymeric composition can include a first ethylene-based copolymer and a second ethylene-based copolymer. The first ethylene-based copolymer can have a weight percent of ethylene-derived units based on a weight of the polymeric composition (EA) ranging from about 35 wt % to about 52 wt % and a weight-average molecular weight (MwA) of less than or equal to 130,000. The second ethylene-based copolymer can have a weight percent of ethylene-derived units based on the weight of the polymeric composition (EB) ranging from about 65 wt % to about 85 wt % and a weight-average molecular weight (MwB) of less than 130,000.
