The polymers are blocky copolymers having semicrystalline ethylene sequences and amorphous or low crystallinity propylene sequences. The polymers are preferably prepared using metallocene-based catalyst systems but without the use of a chain shuttling agent. The polymers may have higher melting temperatures than previously known random copolymers or blocky copolymers prepared with chain shuttling agents having similar comonomer contents. The polymers include both ethylene-rich and propylene-rich copolymers.

Ethylene copolymers, methods for their production, and use

Provided herein are ethylene copolymers, methods for making such copolymers, and compositions made from such copolymers. The ethylene copolymers have 70 wt. % to 85 wt. % of units derived from ethylene and at least 12 wt. % of units derived from at least one α-olefin having 3 to 20 carbon atoms. The copolymers preferably further have a weight-average molecular weight (Mw) ranging from about 50,000 to about 200,000 g/mol, melting point of at least 100° C., ratio of Mw/Mn of about 1.5 to about 3.5, a content of group 4 metals of no more than 25 ppm, and a ratio of wt ppm Group 4 metals/wt ppm Group 5 metals of at least 3. Such copolymers may be particularly useful as viscosity modifiers for lubricating oil compositions.

Lubricating oil compositions and method for making them

Provided are ethylene propylene copolymers compositions thereof and methods for making the same. The composition may include an ethylene copolymer, comprising 40 wt % to 70 wt % of units derived from ethylene, and at least 30 wt % of units derived from at least one α-olefin having 3 to 20 carbon atoms. The composition can have a melting point (Tm) in ° C., as measured by DSC, that satisfies the relation: Tm>3.4×E−180, where E is the weight % of units derived from ethylene in the copolymer. The composition can also have a Mw/Mn ratio of about 1.5 to about 3.5. The composition can further have a content of Group 4 metals derived from a catalyst of 25 ppm or less.

Polyolefin-derived dispersants

Ethylene-C 3 -C 10 alpha olefin copolymers, dispersants and lubricating oils/fuel compositions incorporating dispersants, and related methods are generally described herein. The copolymer may comprise ethylene-derived units and C 3 -C 10 alpha-olefin-derived units. The C 3 -C 10 alpha-olefin-derived units may have a carbon number from three to ten. For example, the C 3 -C 10 alpha-olefin-derived units may be propylene-derived units.

Process for producing α-olefin polymer, α-olefin polymer, and lubricating oil composition

Provided is a method of producing an α-olefin polymer including a step of polymerizing one or more kinds of α-olefins each having 6 to 20 carbon atoms with a catalyst obtained by using a specific transition metal compound. By the method, an α-olefin polymer having a viscosity suitable for use in a lubricating oil can be produced on an industrial scale with ease, and further, the characteristics of the product can be widely changed through the control of reaction conditions.
