In the presence of organic peroxide, the radical polymerization of (MP)_2PT in toluene took place. The kinetics of (MP)_2PT polymerization and the ESR spectra of LPO-(MP)2PT-MNP systems were determined respectively.展开更多
The polymerization of methyl methacrylate (MMA) initiated by organic peroxide and polymerizable aromatic tertiary amine such as N, N-di (2-α-methylacryloyloxy propyl)-p-toluidine (MP)_2PT binary system has been studi...The polymerization of methyl methacrylate (MMA) initiated by organic peroxide and polymerizable aromatic tertiary amine such as N, N-di (2-α-methylacryloyloxy propyl)-p-toluidine (MP)_2PT binary system has been studied. It was found that the (MP)_2PT promotes MMA polymerization, and the kinetics of MMA polymerization fits the radical polymerization rate equation. Based on the ESR studies and the end-group analysis the initiation mechanism is proposed.展开更多

Two novel one- and two-dimensional network structure bismuth(III) complexes with N,N-di(2-hydroxylethyl)- aminodithiocarboxylate, {Bi[S2CN(C2H4OH)2]2[1,10-Phen]2(NO3)}3H2O (1) and {Bi[S2CN(C2H4OH)2]3}2 (2) were synthe...Two novel one- and two-dimensional network structure bismuth(III) complexes with N,N-di(2-hydroxylethyl)- aminodithiocarboxylate, {Bi[S2CN(C2H4OH)2]2[1,10-Phen]2(NO3)}3H2O (1) and {Bi[S2CN(C2H4OH)2]3}2 (2) were synthesized. Their crystal and molecular structures were determined by X-ray single crystal diffraction analysis. The crystal 1 belongs to monoclinic system with space group C2/c, a=1.6431(7) nm, b=2.4323(10) nm, c=1.2646(5) nm, =126.237(5)o, Z=4, V=4.076(3) nm3, Dc=1.757 Mg/m3, =4.598 mm-1, F(000)=2156, R=0.0211, wR=0.0369. The structure shows a distorted square antiprism configuration with eight-coordination for the central Bi atom. The one-dimensional chain structure was formed by H-bonding interaction between hydroxyl group of N,N-di(2-hydroxylethyl)aminodithiocarboxylate ligands and crystal water. The crystal 2 belongs to monoclinic system with space group P2(1)/c, a=1.1149(4) nm, b=2.1274(8) nm, c=2.2107(8) nm, =98.325(8), Z=4, V=5.188(3) nm3, Dc=1.920 Mg/m3, =7.315 mm-1, F(000)=2944, R=0.0565, wR=0.0772. The structure shows a distorted square antiprism configuration with eight-coordination for the central Bi atoms. The two-dimensional network structure was formed by H-bonding interaction between adjacent molecules.展开更多
