Abstract:
The present disclosure relates to a novel aqueous composition of a structurally modified, water soluble polymer suitable for papermaking and to a method for manufacturing it. The method includes cleaving a backbone of the acrylamide polymer by a degradation agent and cross-linking the acrylamide polymer subjected to cleaving by using a polyfunctional cross-linking agent.
