Claim:
1. A process comprising: a) obtaining a first batch of monomers selected from the group consisting of acrylates with a molecular weight equal to or less than butyl acrylate, methacrylates with a molecular weight equal to or less than butyl methacrylate and combinations thereof; b) obtaining a second batch of monomers selected from the group consisting of acrylates with a molecular weight greater than butyl acrylate, methacrylates with a molecular weight greater than butyl methacrylate and combinations thereof; c) preparing a mixture comprising the first batch of monomers and the second batch of monomers wherein the second batch is greater than 50% by weight of the mixture; d) polymerizing the mixture to produce an ultra high molecular weight polymer includes at least 25,000 repeating units; and the ultra high molecular weight polymer has a molecular weight greater than five million, the polymer providing drag reduction in heavy crude oil as it flows through a pipeline during use.
