2-N-Pyrrolidonoethyl acrylate(PyEA) and 2-N-pyrrolidonoethyl methacrylate (PyEMA) were synthesized by reaction of N-2-hydroxyechyl pyrrolidone with corresponding acryloyl chlorides in the presence of triethylamine. The polymerization of PyEA

PyEMA were carried out at 40℃

using N

N-dimethylaminoethyl methacrylate(DMAEMA)-potassium persulfate (KPS) system as an initiator. Kinetic study showed that the rate equation of polymerization (Rp) could be expressed:Rp = Kp[DMAEMA]0.5[KPS]0.5[PyEA] orRp= Kp[DMAEMA]0.5[KPS]0.5[PyEMA] The overall activation energy for the polymerization was estimated to be 44.9 KJ/MOL

52.7 KJ/mol for PyEA or Py EMA respectively.
