ABSTRACT:
A pour depressant polyalkylacrylate comprising an interpolymer of (A) C.sub.1 -C.sub.15 alkylacrylate and (B) C.sub.16 -C.sub.22 alkylacrylate, said interpolymer having an average molecular weight of between about 1000 and 25,000, an A:B weight ratio of between about 90:10 and 50:50, an average alkyl side chain length between about 11 and 16 carbons, and prepared under neat conditions; a lubricating oil composition thereof comprising a major amount of lubricating oil and between about 0.005 and 10 wt.% of the interpolymeric pour depressant and between about 0.5 and 30 wt.% of a viscosity index improving ethylene-propylene copolymer of a molecular weight between about 10,000 and 150,000, a propylene content of 20 to 70 mole% and polydispersity index of less than 5; and a method of improving component compatibility, pour depression, and viscosity index comprising admixing a major amount of hydrocarbon lubricating oil with a minor amount of the interpolymeric polyalkylacrylate and ethylene-propylene copolymer.
