Summary. The relationships between lateral force and viscoelastic properties of amorphous polymer surfaces with Tgs lower and higher than room temperature (295K, RT) and their blend systems have been studied on the basis of lateral force microscopic (LFM) measurement. Under the conditions of scanning rate of 102105nmsec-1, normal load of 5nN and RT, the lateral forces of poly(methyl methacrylate)...

The surface enrichment of blend films of poly(methyl methacrylate) (PMMA) and poly(vinyl acetate) (PVAc) cast from various solvents has been investigated by contact angle, X-ray photoelectron spectroscopic and attenuated total reflection Fourier transform infra-red spectroscopic measurements. The composition of each component was fixed at 50 wt%. The surfaces of miscible PMMA/PVAc blend films are...
