Abstract: The number of components in the blend of poly(n-octudecanyl methacrylate)(P n-OMA)and poly(vinyl acetate) (PVA) was determined by factor analysis and FTIR spectrophoto-metry. The results indicated that it is a compatible system.Three peaks between 1600cm-1 and 1800cm-1 in the (P n-OMA)/PVA system,which correspond to carbonyl group of (P n-OMA)PVA and the interaction of (P n-OMA) with PVA respectively, were revealed by least-square curve-fitting (peak resolving) method.The interaction spectrum was used to analyze theblend system for the magnitude of the interaction as a function of composition.The maximum interacticn was at 60wt% of (P n-OMA).

Key words: Factor analysis, FTIR spectrophotometry, Blend of poly(n-octadecanyl methacrylate) and poly(vinyl acetate)
