Abstract
The dynamic wetting and dewetting behaviour of polyethylene terephthal ate (PET), studied by the Wilhelmy technique, is briefly reviewed. Slo w relaxation effects were observed for PET surfaces. Equilibrium is ac hieved by an evaporative process in the case of advancing contact angl es. The molecular-kinetic theory describes the contact angle-velocity dependence more adequately than the hydrodynamic theory in the case of forced spreading.
