Abstraa-The signifi~t variables in drag reduction have been separated into two classitications, flow variables and solution variables. A theory has been offered which permits prediction of the critical Reynolds number in the turbulent flow of polymer solutions. The theory states that the relaxation

## Abstract A series of linear poly(__N__βethylacrylamide) (PEA) samples varying in molar mass has been prepared by free radical polymerization in the absence and presence of a chain transfer agent and a hydrogel of PEA has been prepared using __N__,__N__βmethylenebisacrylamide (BIS) as crosslinker
