Summary
Chlorinated polyethylene is a commonly used impact modifier for PVC. Because the PVC and CPE are not compatible, the structure, and therefore the properties of their blends strongly depend on processing conditions.
It has been found that the TSD spectra show the structural changes in the PVC-CPE blend well and allow the processes at the phase boundaries to be ascertained. The impact strength values of tested samples can be related to TSD results.
