Abstract

Sum-frequency vibrational spectroscopy was employed to study surface glass transition of

poly(vinyl alcohol) by monitoring the relaxation of rubbing-induced alignment of surface chains with

increase of temperature. The observed chain relaxation is two-dimensional, parallel to the surface. The

surface transition temperature is 58 ( 2 °C, essentially the same as the bulk one.
