Polymers surface morphology

Recent developments have allowed for more detailed studies of polymer surface morphology by ESCA. Angle-resolved ESCA (ARXPS) allows for providing chemical compositions from shallower depths. By varying the angle of incidence different depths can be probed, and procedures have been developed to arrive at three-dimensional reconstruction of the surface. An example is shown in Figure 2, where a PVC/PMMA polymer blend has been analysed using such an approach [9].

Polymer surface morphology will affect the value of gloss. Processing parameters as well as mold flnish (for various molding operations) or chill roll finish (in cast film operations) will also affect gloss values. Typically, rubber-modified polyolefins have a lower gloss than highly crystalline polyolefins.
