New sterically hindered piperidine derivatives (10-17) were prepared by ringopening reaction of various oxiranes with the commercially available 2,2,6,6-tetramethylpiperidin-4-yl-amine. By the addition of these sterically hindered piperidine derivatives (10-17) on 2-methylacryloyl isocyanate, eight novel multifunctional methacryloyl ureas, containing a hindered piperidine and a hydroxyl group (M1-M8) were synthesized. Five of these new multifunctional methacryloyl urea monomers (M1-M5) were homopolymerized, and copolymerized with styrene and methyl methacrylate by AIBN as initiator at 70°C. The new methacryloyl urea monomers (M1-M8) and their polymers (P1-P13) were characterized by Fourier transform infrared and nuclear magnetic resonance spectroscopy and by gel permeation chromatagraphy.
