Evaluation of Rubber-PVC Blends Structure and Properties Using Scanning Acoustic Microscope
Ozone-resistant materials can be obtained by mixing butadiene-nitrile rubber (BNR) with polymers or elastomers. It has been established that depending on the rubber polar butadiene-nitrile groups content and BNR/PVC ratio, the blends can display the properties of either homo- or heterogeneous systems. In high-compatible blends the PVC forms a developed spatial framework that provides the highest ozone-resistance. Therefore, the investigation of the BNR-PVC blends morphology concerning various BNR/PVC compatibility and BNR/PVC ratios is of considerable importance both for fundamental polymer research and applied polymer material characterization with regard to a deeper understanding of the mechanisms of the ozone-protecting properties formation.
