A B S T R A C T A process for reducing oxidative degradation and cold flow of polymer crumb by immersing the crumb in a non-solvent such as water and/or dusting the crumb with a powder such as calcium carbonate and 2,6 di-t-butylparecresol, 4,4'-methylene-bis-(2,6- di-t-butylphenol) or other antioxidants. A process for reducing fluid flow friction loss in pipeline transmission of a hydrocarbon fluid by providing a continuous source of dissolved polymer therein by injecting polymer crumb or a slurry of polymer crumb and water into the hydrocarbon fluid, whereby the crumb gradually and continuously dissolves during transmission of the crumb through the pipeline.
