Abstract
In this work we have investigated the influence of plasticization (i.e . admixture of low molecular weight additives) on the picosecond range ''fast-dynamics'' of a glass forming polymer, poly(vinyl chloride) (P VC). We have investigated samples of plasticized and pure PVC by inela stic neutron scattering and broadband dielectric spectroscopy. Althoug h the suppression of the beta relaxation by the plasticizer could be c learly verified by dielectric spectroscopy, the neutron scattering spe ctra did not show any change of the fast-dynamics. Therefore our resul ts do not support a relationship between the fast-dynamics observed by neutron scattering and the beta relaxation. (C) 1998 Elsevier Science B.V. All rights reserved.
