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.

Description

technical field [0001] The present invention relates to the improvement of oil / grease and water sizing of cellulosic materials, especially paper products. In particular, the present invention relates to selected polyamines substituted with cellulose-reactive fluorocarbon groups. Background technique [0002] Highly effective compounds or polymers that provide oil / grease and water sizing properties to paper have long been desired. Many grades of paper need to be resistant to both oil / grease and water. The currently commercially available chemical that is said to provide both oil / grease sizing and water sizing properties is not actually a highly effective water sizing agent. When both a high level of oil / grease resistance and a high level of water resistance are required, a separate water sizing must be added with the oil sizing. Oil / grease sizing and water sizing often have a negative impact on each other's performance, so when both oil / grease and wa...
