Dynamic mechanical properties of biphasic PVC/CPE polymer blends of different micromorphology were studied. It was revealed that a considerable interaction existed between the polymers involved in the high‐impact polymer blends. It was established that the most favorable cold impact strength of the high‐impact PVC/CPE alloy was obtained when a structure of mixed morphology had been formed in the course of processing. As indicated by the DMA spectra, more marked plasticizing effect of CPE appeared at a lower thickness of CPE layer among the primary globules, i.e., at a higher extent of wetting the PVC globules by CPE molecules. This phenomenon is manifested by splitting the β‐relaxation transition of PVC.
