Abstract
Biodegradable polymer blends of poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV) and poly(ε-caprolactone) (PCL) blends were prepared with the ratio of PHBV/PCL ranging from 80/20-20/80 by co-dissolving the two polyesters in chloroform and casting the mixture. Differential scanning calorimetry (DSC) and optical microscopy (OM) were used to investigate the miscibility and crysta...

81. Nonisothermal Crystallization and Melting Behavior of a Luminescent Conjugated Polymer... G.Z.Yang, X.L.Chen, W.Z.Wang, M.Wang, T.X.Liu*, C.Z.Li. J. Polym. Sci. Polym. Phys. 45(8), 976-987, 2007.
The nonisothermal crystallization kinetics of a luminescent conjugated polymer, poly(9,9-dihexylfluorene-alt-co-2,5-didecyloxy-1,4-phenylene) (PF6OC10) withthree different molecular weights was investigated by differential scanning calorimetry under different cooling rates from the melt. With increasing molecular weight of PF6OC10, the temperature range of crystallization peak steadily becam...

67. Synthesis and characterization of poly(arylene ether ketone) (co)polymers containing...... F.Wang,T.L.Chen,J.P.Xu,T.X.Liu,H.Y.Jiang,Y.H.Qi,S.Z.Liu,X.Y.Li. Polymer 47(11),4148-4153,2006.
Poly(arylene ether ketone)s containing sulfonate groups were synthesized by aromatic nucleophilic polycondensation of 4,4′-difluorobenzophenone (DFK), sodium 2,5-dihydroxybenzensulfonate (SHQ) and bisphenols. Only low-molecular weight oligomer was obtained when hydroquinone (HQ) was employed as comonomer, while copolymerization of DFK, SHQ, and phenolphthalein (PL) proceeded quantitatively to hig...

11. "Miscibility and crystallization of poly(ethylene succinate)/poly(vinyl phenol) blends". Qiu ZB,* Fujinami S, Komura M, Nakajima K, Ikehara T, and Nishi T.* Polymer 2004; 45: 4515-4521.
Miscibility of biodegradable poly(ethylene succinate) (PES)/poly(vinyl phenol) (PVPh) blends has been studied by differential scanning calorimetry (DSC) in this work. PES is found to be miscible with PVPh as shown by the existence of single composition dependent glass transition temperature over the entire composition range. Spherulitic morphology and the growth rates of neat and blended PES were ...

9. "DSC and TMDSC Study of Melting Behaviour of Poly(butylene succinate) and Poly(ethylene succinate)". Qiu ZB,* Komura M, Ikehara T, and Nishi T.* Polymer 2004; 44: 7781-7785.
The subsequent melting behaviour of poly(butylene succinate) (PBSU) and poly(ethylene succinate) (PES) was investigated using DSC and TMDSC after they finished nonisothermal crystallization from the melt. PBSU exhibited two melting endotherms in the DSC traces upon heating to the melt, which was ascribed to the melting and recrystallization mechanism. However, one melting endotherm with on...

36. Variation of crystallographic parameters in PEEKK with heat treatment temperature. Liu TX, Mo ZS, Zhang HF, Na H, Wu ZW. EUROPEAN POLYMER JOURNAL 33 (6): 913-918 JUN 1997.
Using the wide-angle X-ray diffraction method, the variation of crystallographic parameters of poly(aryl ether ether ketone ketone) (PEEKK) has been studied in different heat treatment temperatures. All the reflections and their intensities as well as their Miller indices are presented in detail according to an orthorhombic system. The investigation indicates that the unit cell parameters a, b, c ...

34. Nonisothermal crystallization behavior of a novel poly(aryl ether ketone): PEDEKmK. Liu TX, Mo ZS, Zhang HF. JOURNAL OF APPLIED POLYMER SCIENCE 67 (5): 815-821 JAN 31 1998.
Nonisothermal melt crystallization kinetics of PEDEKmK linked by meta-phenyl and biphenyl was investigated by differential scanning calorimetry (DSC). A convenient and reasonable kinetic approach was used to describe the nonisothermal melt crystallization behavior, and its applicability was verified when the modified Avrami analysis by the Jeziorny and Ozawa equation were applied to the crystalliz...

Nylon 11/organoclay nanocomposites have been successfully prepared by melt-compounding. X-ray diffraction and transmission electron microscopy indicate the formation of the exfoliated nanocomposites at low clay concentrations (less than 4 wt%) and a mixture of exfoliated and intercalated nanocomposites at higher clay contents. Thermogravimetric and dynamic mechanical analyses as well as tensile te...

19. Thermal degradation behavior of polyamide 6/clay nanocomposites. Pramoda KP, Liu TX, Liu ZH, He CB, Sue HJ. POLYMER DEGRADATION AND STABILITY 81 (1): 47-56 JUL 2003.
This paper focuses on the study of thermal degradation and evolved gas analysis using thermogravimetric analysis (TGA) coupled to Fourier transform infrared (FTIR) spectroscopy, i.e., TG-IR, to study polyamide 6 (PA6) and PA6-clay nanocomposites prepared by melt compounding. The thermal decomposition of PA6 and its clay nanocomposites takes place with the evolution of the cyclic monomer (caprolact...

The triple melting behavior and lamellar morphologies of isotactic polystyrene isothermally crystallized from the glassy state have been investigated by differential scanning calorimetry (DSC), temperature-modulated DSC and transmission electron microscopy (TEM). The combination of thermal analysis measurements and morphological observations indicates that: (1) The lowest endothermic peak, the so-...
