Abstract
PVC/aliphatic ketone systems were investigated by NMR relaxation times such as proton and carbon-13 spin-lattice relaxation time (T1) and proton spin-lattice relaxation time in the rotating frame (T1ϱ). The proton T1 results showed that these systems are homogeneous, while proton T1ϱ indicates the existence of more than one domain.
