Abstract: The crosslinking of water soluble terpolymers P(AM-AA-HPA)in acidic aqueous solution with formaldehyde was studied.It was demonstrated that the crosslinking reactions occurred at the sites of amido bond of acrylamide (AM) and the OH group of β-hydroxypropylacrylate(HPA).The crosslinked film exhibits excellent hydrophilic as well as oil-repelling properties and with incorporation of ZnO can be used as a coating to prepare the printing plate on polyethylene glycol terephthalate substrate.

Key words: terpolymer, polyacrylamide, printing plate
