Aliphatic tertiary amino-group N-substituted acrylamides, N-acryl-N′-methylpiperazine (AMP)and N-methacryl-N′-methylpiperazine (MAMP) were synthesized directly from N-methylpiperazinewith corresponding acryloyl chlorides and characterized by elementary analysis of their picrates,~1H-NMR, IR and MS. AMP did not polymerize with benzoyl peroxide (BPO), but could poly-merize with lauroyl peroxide (LPO). The rate equation of the polymerization was given as R_P=K_P [AMP]~(1.5)[LPO]~(0.5) and the overall activation energy of this polymerization system was 10.8Kcal/mol. The redox nature of LPO with the monomer itself was suggested. Even though AMP and MAMP hardly proceed the polymerization initiated with BPO, butunder lower concentration would form redox system with BPO to initiate the polymerization of MMAreadily. The rate equation of the polymerization of MMA initiated with MAMP-BPO systemwas given as R_P=K_P [MMA] [MAMP}~(0.5) [BPO]~(0.5) and the overall activation energy was 10.2Kcal/mol. The analysis of the obtained polymers confirmed that MAMP not only initiated the poly-merization of MMA by combining with BPO, but also took part in the polymer chains impartingthem with better biocompatibility.
N-methacryl-N’-methylpiperazine (AMP) and N-methacryl-N’-methylpiperazine (MAMP) were synthesized directly from N-methylpiperazine with corresponding acryloyl chlorides and characterized by elementary analysis of their AMPrates not polymerize with benzoyl peroxide (BPO), but could poly-merize with lauroyl peroxide (LPO). The rate equation of the polymerization was given as R_P = K_P [AMP] ~ (1.5) [LPO] ~ (0.5) and the overall activation energy of this polymerization system was 10.8 Kcal / mol. The redox nature of LPO with the monomer itself was suggested. Even though AMP and MAMP hardly proceed the polymerization initiated with BPO, The rate of the polymerization of MMA initiated with MAMP-BPO system was given as R_P = K_P [MMA] [MAMP} ~ (0.5) [BPO] ~ ( 0.5) and the overall activation energy was 10.2 Kcal / m ol. The analysis of the Mm not only initiated the poly-merization of MMA by combining with BPO, but also took part in the polymer chains imparting them with better biocompatibility.
