ABSTRACT:
There is provided a flocculating process, especially for clay-water suspensions, in which high molecular weight polymers of N-loweralkyl substituted acrylamides and methacrylamides are used as flocculating agent. There are also provided novel polymeric flocculating agents which have the property of exhibiting a critical flocculation temperature, below which they will cause flocculation of suspended solids but above which they are ineffective as flocculants.
