Synopsis
In this paper a report is given on investigations of the temperature and frequency dependence of sidegroup, i. e. methyl group, and segmental motions in polydimethylsiloxane by neutron scattering and proton spin-lattice relaxation experiments. It is concluded that besides the classical types of motional processes a quantum mechanical mechanism, the methyl group rotational tunneling, occurs in this polymeric system.
