    Abstract: An interpolymer of an n-alkylacrylate mixture and an nalkanediol dimethacrylate of from 10 to 18 carbons, said interpolymer having a weight ratio of said n-alkylacrylate mixture to said alkanediol dimethacrylate of between about 99.5: 0.5 to 95:5 and a molecular weight between about 3000 and 100,000 and wherein the alkyl in said n-alkyl mix is of at least 18 carbons and at least 70 wt. % of said alkyl is between 20 and 24 carbons inclusively, the C20 to C24 alkyl group consisting of between about 2 and 65 wt. % of C20 alkyl, between about 18 and 65 wt. % C22 alkyl and between about 8 and 35 wt. % C24 alkyl; and a waxy heavy petroleum fraction containing between 4 and 15 wt. % macrocrystalline paraffin wax having incorporated therein a pour depressing amount of said interpolymer wherein said interpolymer is initially introduced in the waxy heavy petroleum fraction at a temperature above the solution point of the macrocrystalline wax component therein.

    Abstract: A method of preparing a nitroketonized amide by contacting an acid amide of the formula:

    WHERE R1 is an alkenyl group of from 4 to 40 carbon atoms, where R2 and R3 alternately represent hydrogen and an alkenoyl group of from 4 to 40 carbon atoms, with dinitrogen tetroxide and oxygen, at mole ratios of acid amide to dinitrogen tetroxide to oxygen of from 1:2:2 to 1:4:60.
