1. The production of a gel which comprises incorporating into a normally liquid hydrocarbon a small proportion effective to form a gel of at least one liquid hydrocarbon dispersible copolymer selected from the group consisting of rubbery and solid copolymers compound represented by the formula WHEREIN R is selected from the group consisting of hydrogen, alkyl and alkoxy; and R' is selected from the group consisting of WHEREIN X is selected from the group consisting of hydrogen, alkyl and a halogen, Y is selected from the group consisting of hydrogen, alkyl and aryl; wherein R'' is selected from the group consisting of alkyl, cycloalkyl, aryl, alkaryl, and aralkyl; the total of the carbon atoms in R and R' when R' does not contain R'' is two to eight; and wherein when R'' is present the total of the carbon atoms in R and R' is two to thirteen and a copolymerizable compound containing a basic tertiary amine group selected from the group consisting of vinylpyridines, vinylquinolines and their nuclear-alkyl-substituted derivatives containing not more than a total of 12 carbon atoms in the nuclear-substituted groups, said copolymerizable compound containing not more than a total of 12 carbon atoms in the hydrocarbon groups attached to the nitrogen atom, said copolymer having been prepared using 0.25-8 parts per 100 by weight of total monomeric material.
