| Abstract: | The polymerization of dimethylaminoethyl methacrylate (DMAEMA) initiated by lauryl peroxide (LPO) has been investigated. The rate equation of the polymerization was obtained as Rp = Kp DMAEMA]1.5 LPO]0.5, and the overall activation energy of polymerization was determined as low as 9.7kcal/mol (40-70℃). It is suggested that the redox system from the tertiary amino group of the monomer and LPO initiated the polymerization of monomer itself. |
