Ethylene copolymers for hydrocarbon applications

A method of treating a hydrocarbon mixture that includes paraffin wax and at least one reactive moiety, comprising:

• providing an ethylene acrylic ester terpolymer having about 5 to about 40 weight % of alkyl acrylate and a moiety reactive with at least one reactive moiety in the hydrocarbon mixture, wherein the ethylene acrylic ester terpolymer is formed from (A) a first monomer of ethylene, (B) a second monomer selected from the group consisting of vinyl acetate, alkyl acrylic esters, alkyl (meth)acrylic esters and combinations thereof, and (C) a third monomer having the moiety reactive with at least one reactive moiety in the hydrocarbon mixture, the third monomer selected from the group consisting of maleic anhydride, maleic acid diesters, glycidyl acrylate, glycidyl methacrylate, glycidyl vinyl ether and combinations thereof;
• and
• mixing the ethylene acrylic ester terpolymer with the hydrocarbon mixture that includes paraffin wax and at least one reactive moiety.
