Applications of methacryloyl isocyanate for coatings

Synthesis and Polymerization of New Methacryloyl Ureas Carrying a Hindered Piperidine and a Hydroxyl Group

“…Either end group of the molecule may be reacted independently, leaving the other func- tion available for subsequent reactions. 2-Methylacryloyl isocyanate reacts cleanly with amine or hydroxy compounds to form vinyl-substituted acyl ureas or carbamates (18,24,25). Its high reactivity allows the easy introduction of vinyl functionality into various compounds, which have hitherto resisted such treatment.…”

“…MAI was selected for this purpose. It has a polymerizable double bond and a highly reactive acyl isocyanate group (22)(23)(24). Either end group of the molecule may be reacted independently, leaving the other func- tion available for subsequent reactions.…”

Radical polymerization of new functional monomers derived from methacryloyl isocyanate and urea

“…Methacryloyl isocyanate (MAI) (Nippon Paint Co.) was prepared from methacrylamide and oxalyl chloride as described in previous literature, [1][2][3][4] and purified by distillation at reduced pressure (52-53°C/39 mmHg). Urea and sulfonyldiphathalic anhydride were purified by recrystallization from methanol and acetic anhydride, respectively.…”

“…Functional monomer/polymer systems derived from acrylates and methacrylates are used extensively in adhesives, coatings, electronics, medical and photographic materials. 1 Methacryloyl isocyanate (MAI) is a unique versatile hetero-functional molecule, combining in the same molecule an aliphatic acylisocyanate function and a methacylic polymerizable double bond. [2][3][4][5][6][7][8][9][10][11][12] The vinyl group can be easily polymerized by free radical polymerization.…”

Radical polymerization of new functional monomer: Methacryloyl isocyanate containing 4-chloro-1-phenol

“…[1][2][3][4][5][6][7][8][9] Either end group of the molecule may be reacted independently, leaving the other function available for subsequent reactions. Functional polymers have become increasingly important because of their diverse applications such as polymeric reagents and crosslinking resins, etc.…”
