摘要
The addition of an amine functional poly(vinyl alcohol) in a process for making recycled paper products results in improvements in both the wet and dry strength of the resultant products. The amine functional poly(vinyl alcohol) used in the process is formed by the hydrolysis of vinyl acetate/vinyl amide copolymers or vinyl acetate/allyl amine copolymers, or optionally may be formed by the reaction of poly(vinyl alcohol ) with an amino-aldehyde dialkyl acetal.
