摘要

Radical Polymerization of N-[(1-n-butoxycarbyl) ethyl] ethymaleimide (PBAM) was syntheSized by solution polymerization with 2,2'-Azobis(isobutylronitrile)(AIBN) as radical initiator The resulting polymer(PBAM)was characterized by infrated spectroscopy(IR),themogravimetry (TG) ,and differential thermal analysis (DTA).The initial decomposition temperature of PBAM is 321.6 deg C ;the glass transition temperature of PBAM was 240.5 deg C.The dffects of solvent ,temperature,initiator concentration ([I]) ,and monomer concentration([BAM]) on polymerization were also discussed.The overall activation energy (E_a) of homopolymerization was determined(E=93.5kJ/mol) .It was revealed that the rate of polymerization (R_p) can be expressed as R_p x [I]~(0.58)[BAM] .
