Abstract
Two novel phosphonated methacrylate monomers were successfully syn- thesized and subsequently incorportated into adhesion/anticorrosive coatings. Specifi- cally, they were propyl N,N-tetramethyl-bis(phosphonate)-2-hydroxyl-bis(methylene) amine methylmethacrylate (MAC3NP2) and 2-(2,2-bis(diisopropoxyphosphoryl) ethoxy)-methylmethacrylate, (MAC3P2). The phosphonic forms of each monomer were blended with � 85% w.w acrylates (tripropyleneglycol-diacrylate and hexanediol-dia- crylate) and 6% w.w of the photo sensitive initiator Darocur V R . Along with a monophosphonic monomer synthesized in a previous publication (MAC3P), they were polymerized on Q-panels under ultraviolet light, and then subject to the salt spray test (ca. 0.5 mol/L NaCl at 35 � C) for a duration of up to 50 days. The results indicate that acrylate blends with low concentration of the bisphosphonic compound MAC3P2 have excellent resistance to corrosion, thus excellent adhesive properties. Impor- tantly, these coatings were formed without the use of a hydrophobic polymer matrix or solvents. V V C 2008 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 46: 7972-7984,
