Abstract
Crude oils, lubricating oils or fuel oils have their flow point improved by adding to the crude oil, lubricating oil or fuel oil a minor proportion by weight of a polymer containing the repeating units: ##STR1## where x is an integer and y is 0 or an integer and wherein in the total polymer x+y is at least two.
Claims3
A composition consisting of a major proportion by weight of a fuel oil and 0.0001 to 5 wt. % by weight of a itaconate or citraconate homopolymer flow improver additive containing the repeating units:
- ##STR6## wherein x is an integer and R.sup.1 and R.sup.2 represent a C10-C30 alkyl and the polymer has a molecular weight of 1,000 to 500,000.
