Polystyrene , segmental mobility

In the absence of solvent, the influence of the surface on the segmental mobility can be deduced by measuring the temperature dependence of the spectral line shape in the presence and absence of the surface. The temperature dependence of bulk poly(vinyl acetate) is shown in Figure 3, and of bulk polystyrene... [Pg.2]

Many polymers are themselves brittle at room temperature. For these polymers to become more pUable, additives called plasticizers that allow segmental mobility, and consequently segmental flexibility, are added. For syn-tiietic pol)miers such as poly(vinyl chloride) (PVC) and polystyrene (Figure 13), plasticizers are added that allow tiie polymers to be flexible. [Pg.1041]
