PS/PPSQ blends with different compositions were prepared by two methods: (1) casting film of PS/PPSQ from the solution of two polymers, and (2) PS/PPSQ blends by in situ polymerization. After studying by solid-state NMR, PS and PPSQ in the casting films are miscible on the scale o...
Through 40 years' efforts, we have developed into a professional refrigeration company with considerable scale, reputation and influence in China, serving well-known local enterprises. Good quality and reliable service help us gain credibility all over the world, and ...
After studying by solid-state NMR, PS and PPSQ in the casting films are miscible on the scale of several thousand nanometers. Miscibility of PS/PPSQ blends obtained by the second approach was investigated by DMA, SEM, x-ray energy spectrometer, x-ray diffraction, and fluorescence techniqu...
