关键字：controlled ring-opening polymerization (CROP); reversible addition-fragmentation chain transfer (RAFT); "living"/controllable polymerization; star block copolymer;
Reversible addition-fragmentation chain transfer (RAFT) polymerization is a more robust and versatile approach than other living free radical polymerization methods for synthesis of well-defined homo-, gradient, block, star-shaped and more complex structural polymers, like micro(nano)gels and polymer brushes. Thus the resultant polymers with thiocarbonylthio-terminated groups are readily tailored ...

33. Nonisothermal crystallization kinetics of poly(beta-hydroxybutyrate). An YX, Dong LS, Mo ZS, Liu TX, Feng ZL. JOURNAL OF POLYMER SCIENCE PART B-POLYMER PHYSICS 36 (8): 1305-1312 JUN 1998.
Kinetics of nonisothermal crystallization of poly( beta-hydroxybutyrate) from melt and glassy states were performed by differential scanning calorimetry under various heating and cooling rates. Several different analysis methods were used to describe the process of nonisothermal crystallization. The results showed that both Avrami treatment and a new method developed by combining the Avrami equati...

European Polymer Journal 2009, 45, 1659-1667
The novel comb-type biodegradable graft copolymers based on e-caprolactone and L-lactide were synthesized. Firstly, 2-oxepane-1,5-dione (OPD) was synthesized by the Baeyer–Villiger oxidation of 1,4-cyclohexanedione, and wassubsequently copolymerized with e-caprolactone (CL) to produce poly(2-oxepane-1,5-dione-co-e-caprolactone) (POCL) catalyzed by stannous(II) 2-ethylhexanoate in toluene. Th...

In this report, protein repelling silicone hydrogels with improved hydrophilicity were prepared by photo-polymerization of silicone-containing monomer and glycidyl methacrylate followed by grafting zwitterionic amino acids. The grafted silicone hydrogels possessed excellent hydrophilic surfaces due to the enrichment of amino acids, which was confirmed by attenuated total reflectance Fourier transf...

45. X-ray crystallographic structure of meta- and para-dimethyl ester of pyromellitic acid. Huang WX, Liu TX, Gao LX, Zhang X, Xu JP, Ding MX. CHINESE JOURNAL OF POLYMER SCIENCE 15 (1): 40-49 1997.
The polycrystalline powder of para- and meta-dimethyl ester of pyromellitic acid (PMDE) have been prepared by fractional crystallization, and their crystal structures have been determined by Wide-Angle X-ray Diffraction (WAXD). Both p-PMDE and m-PMDE was found to be orthorhombic crystal system, and their unit cell parameters a = 0.840 nm, b = 0.707 nm, c = 1.136 nm and a = 1.032 nm; b = 0.835 nm, ...

37. Crystallization behavior of a novel poly(aryl ether ketone): PEDEKmK. Liu TX, Mo ZS, Wang SG, Zhang HF, Wang JZ, Na H, Wu ZW. JOURNAL OF APPLIED POLYMER SCIENCE 64 (8): 1451-1461 MAY 23 1997.
Isothermal melt and cold crystallization kinetics of PEDEKmK linked by meta-phenyl and biphenyl were investigated by differential scanning calorimetry in two temperature regions. Avrami analysis is used to describe the primary stages of the melt and cold crystallization, with exponent n = 2 and n = 4, respectively. The activation energies are -118 kJ/mol and 510 kJ/mol for crystallization from the...

32. Influence of annealing on structure of poly(aryl ether ether ketone ketone) revealed by SAXS. Liu TX, Mo ZS, Zhang HF, Li G. JOURNAL OF APPLIED POLYMER SCIENCE 69 (9): 1829-1835 AUG 29 1998.
Structural studies of poly(aryl ether ether ketone ketone) (PEEKK) using small-angle X-ray scattering and one-dimensional electron density correlation function methods revealed that its aggregated state structure was significantly influenced by the annealing temperature. The long period L, the average thickness of the lamellae d, the electron density difference between the crystalline and amorphou...

30. Crystal structure and drawing-induced polymorphism in poly(aryl ether ether ketone). IV. Liu TX, Wang SE, Mo ZS, Zhang HF. JOURNAL OF APPLIED POLYMER SCIENCE 73 (2): 237-243 JUL 11 1999.
A new crystal modification induced by strain and denoted as form II exists alongside the dominant form I structure in the uniaxially oriented poly(ether ether ketone) (PEEK) and the related polymers. The crystal structure of form II for PEEK is also found to possess a two-chain orthorhombic packing with unit cell parameters of a equal to 0.475 nm, b equal to 1.060 nm, and c equal to 1.086 nm.
