MIXTURE OF VINYL ADDED POLYMER USEFUL AS FLOCCULANT FOR TREATING SOLID SUSPENDED IN WATER

摘要

The invention relates to mixtures of polymers of vinyl addition, comprising: / p & & p & a.au least one polymer of highly cationic hydrophilic vinyl having a continuation of at least 1000000 and a content of k moles of vinyl monomer incorporated in the cationic polymer, and / p & & p & b.au least one polymer of a hydrophilic vinyl weakly cationic, nonionic, having a continuation of at least 1000000 and a content of k moles of vinyl monomer incorporated in the cationic polymer, k, meaning a number from 0 to 40 included, k, meaning a number of 60 to 100 included, and k - k60. / p & & p & these mixtures can be used as crosslinking agents and dehydration of the aqueous slurry.
