Blends of Natural Rubber (NR) and poly (vinyl chloride) (PVC) were made by the liquid-liquid technique. The analytical study was carried out by the means of Infra- Red spectroscopy. The aim of the research is to locate blend compositions of optimal interaction, between the components. Using frequency method the functional groups of optimal interactions were; C-Cl, C=C, and CH3. The result obtained for establishing the base mole ratio of optimal interaction by means of frequency average deviation for the polymer pair was 0.395. It was noted from this study that there was interaction between the polymer pair and points of the degrees of the polymer pair interactions were indicated.


Key words: Blend, poly (vinyl chloride) (PVC), natural rubber (NR), molar ratios, Fourier-transform infrared spectroscopy (FTIR).
