Two main types of amine-containing initiation systems were studied in this work. In the case of MMA polymerization initiated by BPO-amine (DMT, DHET, DMA) redox systems, it was found that the polymerization rate and colour stability of the polymer for different amine systems were in the following order: DMT≈DHET>DMA. Accordingly, BPO-DMT and BPO-DHET are effective initiators. In the case of MEMA polymerization by amine (DMT, DHET, DMA) alone, it was found that the polymerization rate and the percentage of conversion for these different amine systems were in the following order:SMT≥DHET>DMA.The polymerization rate and the percentage of conversion also increased with increase of DMT concentration.From the kinetic investigation the rate equation Rp=K[DMT]1/2[MEMA]3/2 was obtained,and the overall activetion energy of polymerization was calculated to be 34.3KJ/mol (8.2 Kcal/mol).Moreover,the polymerization of MEMA in the presence of DMT was strongly inhibited by hydroquinone,indicating the polymerization being free radical in nature.From these results,the mechanism of MEMA polymerization initiated by amine was proposed.
