72. Epoxy resin containing poly(ethylene oxide)-block-poly(3-caprolactone). F.L.Meng, S.X.Zheng, T.X.Liu. Polymer, 47(21), 7590-7600, 2006.
An amphiphilic diblock copolymer, poly(ethylene oxide)-block-poly(3-caprolactone) (PEO-b-PCL) was synthesized via the ring-opening polymerization of 3-caprolactone in the presence of a hydroxyl-terminated poly(ethylene oxide) monomethyl ether. The diblock copolymer was incorporated into epoxy thermosets. It is found that the formation of nanostructures of thermosetting blends is quite dependent on...

68. Thermooxidative stability of spectra of fluorene-based copolymers. G.Z.Yang, M.Wu, S.Lu, M.Wang, T.X.Liu*, W.Huang. Polymer 47(13), 4816-4823, 2006.
The origin of the low-energy emission of fluorene-based homo- and copolymers still remains controversial. In this work, the effect of thermal treatment on the emission properties of poly[(9,9-dihexylfluorene)-alt-co-(1,4-phenylene)] (PF6P) and its four derivatives modified by attaching different lengths of alkoxy side chains on the phenylene rings has been systematically investigated. By comparing...

66. The photophysical properties and morphology of fluorene-alt-benzene based conjugated polymer. G.Z.Yang, M.Wang, T.X.Liu*. Frontiers of Chemistry in China. 1(2), 130-137, 2006.
A series of fluorene-alt-benzene based conjugated main chain polymers chemically attached with alkyl side chains of different lengths on phenylene rings were designed and synthesized by a palladium catalyzed Suzuki coupling reaction. The UV-vis absorption and fluorescence spectra, thermal stability of spectral property, phase transition behavior and morphology of the synthesized polymers were inve...

Poly(vinylidene fluoride) (PVDF) and poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV), both semicrystalline polymers, are miscible as shown by the single glass transition temperature over the entire composition range. Morphology of PVDF/PHBV blends was investigated by optical microscopy under two different crystallization conditions. PVDF showed the spherulitic morphology at 150 oC in the P...

Miscibility has been investigated in blends of poly(butylene succinate) (PBSU) and poly(vinyl phenol) (PVPh) by differential scanning calorimetry in this work. PBSU is miscible with PVPh as shown by the existence of single composition dependent glass transition temperature over the entire composition range. In addition, the polymer-polymer interaction parameter, obtained from the melting depressio...

8. "Miscibility and Crystallization Behavior of Biodegradable Blends of PBSU and PCL". Qiu ZB,* Komura M, Ikehara T, and Nishi T.* Polymer 2003; 44: 7749-7756.
Poly(butylene succinate) (PBSU) and poly(ε-caprolactone) (PCL) blends, both biodegradable chemosynthetic semicrystalline polyesters, were prepared with the ratio of PBSU/PCL ranging from 80/20 to 20/80 by co-dissolving the two polyesters in chloroform and casting the mixture. The miscibility and crystallization behaviour of PBSU/PCL blends were investigated by differential scanning calorim...

6. "Crystallization Behaviour of Biodegradable Poly(ethylene succinate) from the Amorphous State". Qiu ZB,* Ikehara T, Nishi T.* Polymer 2003; 44: 5429-5437.
Nonisothermal and isothermal crystallization kinetics of biodegradable poly(ethylene succinate) (PES) from the amorphous state were studied by differential scanning calorimetry (DSC). For the nonisothermal crystallization, there were two crystallization exotherms upon heating from the amorphous state. One major crystallization exotherm located at low temperature corresponded to the real cold...

5. "Miscibility and Crystallization of Poly(ethylene oxide) and Poly(ε-caprolactone) Blends". Qiu ZB,* Ikehara T, Nishi T. Polymer 2003; 44: 3101-3106.
Blends of poly(ethylene oxide) (PEO) with poly(ε-caprolactone) (PCL), both semicrystalline polymers, were prepared by co-dissolving the two polyesters in chloroform and casting the mixture. Phase contrast microscopy was used to probe the miscibility of PEOB/PCL blends. Experimental results indicated that PEO was immiscible with PCL because the melt was biphasic. Crystallization of PEO/PCL ...

4. "Melting Behaviour of Poly(butylene succinate) in Miscible Blends with Poly(ethylene oxide)". Qiu ZB,* Ikehara T, Nishi T. Polymer 2003; 44: 3095-3099.
The melting behaviour of poly(butylene succinate) (PBSU) in miscible blends with poly(ethylene oxide) (PEO), which is a newly found polymer blends of two crystalline polymers by our group, has been investigated by conventional differential scanning calorimetry (DSC). It was found that PBSU showed double melting behaviour after isothermal crystallization from the melt under certain crystallization ...
