Polyelectrolyte Properties

Polyelectrolyte

Description

 

Polyelectrolytes are polymers whose repeating units bear an electrolyte group. Polyelectrolyte properties are thus similar to both electrolytes and polymers, and are sometimes called polysalts. Polyelectrolytes are classified into weak polyelectrolyte and strong polyelectrolyte. A 'strong' polyelectrolyte is one which dissociates completely in solution for most reasonable pH values. Weak polyelectrolytes are not fully charged in solution, and moreover their fractional charge can be modified by changing the solution pH, counterion concentration, or ionic strength. Polyelectrolytes which bear both cationic and anionic repeat groups are called polyampholytes. Polyelectrolytes are highly versatile products which enhance the performance of a wide range of industrial applications and essential processes right from water purification, oil recovery, colour removal, paper making, mineral processing and a host of other uses. Polyelectrolytes are both flocculants as well as de­flocculants depending upon the molecular weight.
