SYNTHESIS AND POLYMERIZATION OF N- ACRYLOYL - N' - PHENYL UREA AND ITS DERIVATIVES

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.
