crosslinked poly(acrylic acid)s were prepared using two types of crosslinker by precipitation polymerization method in a binary organic solvent. n,n’-methylenebisacrylamide (mba) and polyethylene glycol dimethacrylate (pegdma-330) were used as low-molecular weight and long-chain crosslinkers, respectively. the effect of various types of crosslinkers on polymer characteristics (i.e., gel content...

We measured the α-relaxation in trehalose glass by using photon correlation spectroscopy(PCS). The α-relaxations of trehalose glass showed a crossover from stretchedto compressed-exponential relaxations as the temperature increased. From the Raman scattering measurements, we found that the unusual compressed-exponential relaxation in trehalose glass was caused by the change of glycosidic linkag...

This paper presents a study of the flow and thermal structures in the molten glass bath of a typical glass melting furnace with a throat but without air bubblers or electric boosting. Different separate effects on the flow structure of the glass melt are simulated, but only the glass melt is considered. The net heat flux distribution is imposed at the combustion space/glass melt interface, and ...
