Effects of molecular characteristics of water soluble polymers on drag reduction were investigated by studying changes in the drag reduction efficiency of long chain vinylic polymers, having an identical polymeric backbone, with changes in the chemical nature of their functional groups and studying the effect of conformational changes of a simple polymer on its drag reduction efficiency by changing the pH or adding salt to the solution. The polymers studied were polyacrylamide, hydrolized polyacrylamide, polyacrylhydrazide and polystyrene sulfonate. Modified author abstract
