ABSTRACT:
A water-dispersible oil/grease-sizing and water-sizing agent that provides oil/grease and water-sizing for paper and other cellulosic materials. The agent works effectively for both oil/grease and water sizing at high temperatures. The polymeric agent's key features include a polyamine component which is a repeating monomer unit with cellulose-reactive and fluorinated groups substituted on the polyamine.
