Abstract
A stabilized paraffin inhibitor/pour point depressant (PI/PPD) product formulation is described which includes a copolymer having a monomer selected from the group consisting of alkyl acrylate polymers, alkyl methacrylate polymers, and combinations thereof, where the copolymer comprises vinyl acetate and the product includes an ethylene-based copolymer. The presence of the vinyl acetate stabilizes the product to prevent or inhibit the ethylene-based copolymer from separating out of the product. The product is useful to reduce paraffin deposition and/or improve flow characteristics of petroleum fluids, such as crude oil.
