Polyelectrolyte polymers—Types, forms, and function
The performance of a friction-reducing polymer is dependent on several factors. Probably, the most critical factor in developing polyacrylamide inverse emulsion friction reducers is the quality of the water used in the operation. The simplest situation consists of the use of freshwater for the make down of the friction reducer.
