摘要： 聚甲基丙烯酸正十八酯[P(n-OMA)]是梳状聚合物,玻璃化温度很低(173K),与其他聚合物共混的热行为的研究需在液氮下进行.本文应用Koenig的因子分析法和FTIR光谱法[1-3],在常温下判别了P(n-OMA)与聚醋酸乙烯酯(PVA)的共混相容性,用分峰技术准确定量了它们的相互作用,讨论了影响相互作用的因素。并用DTA谱验证了所得的结论.

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)
