Molecular weight distribution of A_2-B_2 type condensation polymers in the presence of capping monomer C

引用

Science China Chemistry 1996年第2期39卷 160-170页

作者：张连来廖琦顾宜江璐霞蔡兴贤 Department of Polymer Science and Materials Sichuan Union University Chengdu 610065 China

The molecular weight distribution of A2-B2 type condensation polymers in the presence of capping monomer C has been derived with statistical calculation and Monte Carlo simulation methods. The Monte Carlo simulation result agrees with that of statistical calculation. The number distribution function and weight distribution function of seven types of molecules existing in A2-B2-C system have been obtained. The effect of reactivity of capping monomer C on these distributions are discussed.

Synthesis, Characterization of A Novel Polymeric Reaction monomer for Preparing Highly Fluorescent Rare Earth Polymer Materials

Journal of Rare Earths 2007年第S1期25卷 45-48页

作者：西鹏顾晓华夏磊程博闻周游 Tianjin Municipal Key Laboratory of Fiber Modification and Functional Fiber Tianjin Polytechnic University College of Materials Science and Engineering Donghua UniversityState Key Laboratory for Modification of Chemical Fibers & Polymer Materials

A novel polymeric reaction monomer (NPRM) for preparing highly fluorescent rare earth polymer materials was synthesized via interface and coordinating reaction. The composition and structure of the NPRM and intermediate product (ligand) were characterized through the Fourier transform infrared spectroscopy (FT-IR), carbon-nuclear magnetic resonance spectrum (13CNMR), Mass spectra (MS), and element analysis data. The results showed that the composition and structure of NPRM agreed with that of anticipated product. The NPRM was composed of two important sections. Section 1 was able to provide excellent fluorescent properties for final rare earth polymer material through the effect energy transfer between ligand and rare earth ion; Section 2 would endow with the NPRM excellent polymeric active and form highly fluorescent rare earth polymer material. Fluorescent properties of the NPRM were also researched via a CARY ECLIPSE fluorescent spectrometer. The results showed that the NPRM possessed excellent luminescent properties. The corresponding emission peaks based on the 5D0→7F1(601.6 nm), 5D0→7F2(625.0 nm), 5D0→7F3(660.5 nm) and 5D0→7F4(706.3 nm) transitions for Eu3+ were observed. The strongest emission peak was at 625 nm, which belonged to 5D0→7F2 transition.

THE CHARACTERISTICS AND MOTION MODEL OF INSULIN monomer

Science China Chemistry 1992年第4期35卷 418-428页

作者：梁栋材常文瑞王大成张季平 National Laboratory of Biomacromolecules Institute of Biophysics Academia Sinica Beijing 100080 PRC

The extensive conformational comparisons among the determined structures of the differeat species and crystal forms of insulin and the varied insulin derivatives were performed by using the least-squares superimposition technique and the graphics technique. The results of the investigation showed that the structure of molecule I in 2Zn insulin was closer to that of the natural monomer; the conformational difference between two molecules of a dimer came out during dimerization and it was further improved and stabilized during the hexamerization and packing of hexamers in crystal; through the hinge peptides, such as A10, B4, B8, B24, B20 and B23, there was a flexible relative motion among the structural segments in the insulin molecule, and the residues at the B-chain C-terminal might have a shift of more than 10; the mobility for each residue side-chain was very different due to the different surroundings.

A new procedure has been developed successfully to prepare the maleimide-terminated poly (arylene ether sulphone ) oligomers. It was condueted by the aromatic nucleophilic substitution of the chloro-terminated poly (arylene ether sulphone) oligomer by an endblocking monomer, N-(4-hydroxyphenyl) maleimide. The reaction and structure of the product were confirmed by FT-IR. 1H-NMR and elemental analysis.

Hyperlipidemia （HLP） is the No.1 risk factor for patients with atherosclerosis （AS） and is directly related to the occurrence of coronary artery disease （CAD） and cerebrovascular disease. Therefore, prevention and treatment of AS is of great importance and of practical significance in controlling the incidence and mortality of CAD. With its peculiar syndrome-dependent therapy, traditional Chinese medicine （TCM） has accumulated abundant practical experiences in this field and good clinical effects have been achieved. Chinese herbal medicine, with its particularly unique advantages and high potentials yet to be tapped, displays its huge strength in HLP prevention and treatment. The progress of studies concerning prevention and treatment of HLP by Chinese herbal medicines, in the form of monomers or compound recipes, is reviewed in this paper.
