Rheological and diffusion properties of binary PVC-CPE blends were investigated. The blends were obtained in a rather wide composition range (PVC : CPE = 100/0, 90/10, 80/20, 60/40, 40/60, 20/80, 10/90, 0/100 wt./wt.%). It was concluded from the sorption analysis data that for coating and barrier materials systems with higher PVC content should be regarded more appropriate because of their smaller diffusion coefficients. The rheological analysis showed that all the PVC compositions with CPE
