Three methods for synthesis of N- aCryloyl-N'-phenylurea (APU)

N- methacryloyl - N'- phenyl (or p- tolyl)urea (MPU or MTU) monomershave been inveshgated.(i) MPU and MTU were synthesized by the reaction ofmethacryloyl isocyanate with aniline and p- toluldine resghvely;(ii) MPU wassynthesized from the reaetion of methacryloyl chloride and phenylurea;(iii) APUand MPU were syntheSis via the reaction of apltalde and methacrylalinde withphenylisocyanate reSwtvely. These monomers were charactized by elemental ana-lysis

1H-NMR and FT-IR spectra. In the presence of AIBN or BPO

APU

MPU

MTU will polymerize and copolymerize with MMA and MA as well. The thermo behavior of polymers and copolymers was measured by TGA and DSC respectively.
