Supercritical Carbon Dioxide Assisted Solid-State Grafting Process of Maleic Anhydride onto Polypropylene
The work reported in this paper aimed at exploring the advantages of using supercritical carbon
dioxide (scCO2) as an environmentally benign solvent and swelling agent for carrying out the
grafting process of maleic anhydride onto polypropylene in the solid state. The effects of scCO2
on the melting temperature and melting enthalpy of an isotactic polypropylene (iPP) were
investigated first in...

The effects of salt concentration on ion state and conductivity in comb cross-linked polymer electrolytes
A new type of comb cross-linked polyurethane/acrylate polymer was designed. The polymer has sparse network structure with many long comb molecule chains. A new solid polymer electrolyte (SPE) was prepared based on the polymer. The salt in the solid polymer electrolytes has different existent states with different salt contents. With increase of salt concentration, the ion pairing gradually becomes...

77. Solid State 19F NMR Study of Crystal Transformation in PVDF and its Nanocomposites. P.K.Pallathadka, S.S.Tay, T.X.Liu, P.Sprenger. Polym. Eng. Sci. 46(12), 1684-1690, 2006.
The polymorphism of poly(vinylidene fluoride) (PVDF) and its nanocomposites was studied by means of solid state nuclear magnetic resonance spectroscopy. 13C cross polarization magic angle spinning (13C CP MAS) NMR spectra were recorded using simultaneous high-power decoupling on both the proton and fluorine channels. Both 1H - 13C and 19F - 13C CP experiments were conducted, givin...

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...
