Abstract

The polymerization of methyl methacrylate(MMA) in the presence of N-hydroxyethyl-N-methyl-para-toluidine(HMT) initiated with organic peroxide

such as benzoyl peroxide (BPO)

lauroyl peroxide(LPO)

has been studied. It was found that HMT can increase the rate of polymerization Rp and decrease the overall activation energy of polymerization E

. The values of E0 reduced from 85.8 KJ/mol using BPO alone to 41.3 KJ/mol using BPO/HMT as initiator. The rate equations of MMA polymerization were determined as follows: Rp=K[BPO]0.48[HMT]0.48[MMA]1.02 Rp=K[LPO]0.47[HMT]0.46[MMA]0.98 It fits well to the equation of polymerization with redox initiation system. UV spectrum end group analysis of polymer obtained revealed the presenceof HMT moiety in the end group. Accordingly

the radicals derived from aromatic amine will initiate monomer to polymerize.
