✦ Synopsis

New functional monomer methacryloyl isocyanate containing 4-chloro-1phenol (CPHMAI) was prepared on reaction of methacryloyl isocyanate (MAI) with 4-chloro-1-phenol (CPH) at low temperature and was characterized with IR, 1 H, and 13 C-NMR spectra. Radical polymerization of CPHMAI was studied in terms of the rate of polymerization, solvent effect, copolymerization, and thermal properties. The rate of polymerization of CPHMAI has been found to be smaller than that of styrene under the same conditions. Polar solvents such as dimethylsulfoxide (DMSO) and N,N-dimethyl formamide (DMF) were found to slow the polymerization. Copolymerization of CPHMAI (M 1 ) with styrene (M 2 ) in tetrahydrofuran (THF) was studied at 60°C. The monomer reactivity ratio was calculated to be r 1 ϭ 0.49 and r 2 ϭ 0.66 according to the method of Fineman-Ross.
