This work is concerned with the effect of an epoxy resin on the properties of rigid poly(vinyl chloride) (PVC). The epoxy resin concentrations of 0, 1, 2, 4, and 6 phr were used to prepare PVC/epoxy polymer blends and the viscoelastic behavior of the blends was investigated by dynamic mechanical thermal analysis and rheometry test. The results revealed that the low molecular weight epoxy resin did not greatly affect the viscoelastic properties of PVC. From the morphological point of view, the smallest droplet size of epoxy dispersed in the polymer blends was found in the sample with 1 phr epoxy resin, and the largest one was for the sample with 6 phr epoxy. The thermal properties of PVC/epoxy blends were investigated using differential scanning calorimetry and thermogravimetric analysis, as well. According to our research, the initial decomposition temperature of PVC was increased about 6°C by the incorporation of epoxy resin. The results of tensile test showed that the addition of epoxy resin decreased the elongation‐at‐break of PVC about 50% in the samples without calcium carbonate and about 25% in the samples containing calcium carbonate. Moreover, the failure mode of PVC was changed from a ductile fracture mode to a brittle fracture mode with the addition of epoxy resin. J. VINYL ADDIT.

The compositions on the basis of PVC, containing dioctyl phthalate as a plasticizer, complex thermal stabilizers – calcium and zinc stearates and adducts of thiophenol and ethanedithiol with gemdiglycidyloxymethylsubstituted cyclopropylvinyl ether as co-stabilizers and biocidal additives were developed. Thermal properties of the developed compositions were investigated and the influence of the synthesized sulfur-containing adducts on the thermal stability and color change of the compositions studied. The tests were carried out to reveal the antifungal activity of adducts in the structure of PVC compositions. It found that the chemical structure of adducts after introduction into the structure of compositions was not essentially changed. The compositions with the participation of adducts as co-stabilizers acquired improved indices on thermal stability, color stability and antifungal activity.
