Atactic polystyrene ( a PS) films cast from solutions of different concentrations in dichloromethane under vacuum conditions were prepared.Their tensile mechanical behavior has been studied.It was found that the tensi...
The morphology of poly(styrene ethylene/butylene styrene)(SEBS) triblock copolymer cast from heptane and toluene was studied by combining atomic force microscopy(AFM) with transmission electronics microscopy(TEM). The...
The effects of physical ageing on the crazing of polyphenylquinoxaline(PPQ E) films were studied. The DSC endothermic peak at the glass transition region of the samples was interpreted in terms of the cohesional entan...
The effect of solvents on the morphology and properties of styrene-butadiene-styrene(SBS, \{Mn=\}99 575, Mw/Mn=1.3, S/B=3∶7) triblock copolymer films was studied in this paper. The solvents used in the study are: e...
