ABSTRACT:
Process for the preparation of water-in-water secondary dispersions of homo- or copolymers of (meth)acryl compounds through the dispersion of fine particle polymers of the type cited in an aqueous solution which contains in dissolved form from 2 to 50 weight percent of a polymer of ethylene oxide and/or propylene oxide having a molecular weight of from 500 to 10,000. The secondary dispersions can be easily diluted with water and are used as flocculants.
