SYNTHESES AND POLYMERIZATION OF ACRYLATES HAVING LACTAM MOIETY
含吡咯烷酮基丙烯酸酯类单体的合成及聚合

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 = KpDMAEMA]0.5KPS]0.5PyEA] orRp= KpDMAEMA]0.5KPS]0.5PyEMA] 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.
