Bimolecular inverse emulsion polymer |
摘要 |
The invention relates to novel, stable bi-molecular cationic inverse emulsion polymers (W/O) with both different molecular weights and cationic activities that are assembled via an "in situ" emulsion polymerization of a high molecular weight cationic polymer in the presence of a low molecular weight polymer in the aqueous phase. The low molecular cationic polymer is produced in a pre-polymerization in solution. The novel, stable cationic water-in-oil emulsion is easy invertible and useful as flocculant, dewatering aid and retention aid in papermaking. |
