以四氢呋喃（THF）和丁酮为溶剂，采用粘度法和差示扫描量热法研究了不同组成的苯乙烯-甲基丙烯酸共聚物（SMA-12和SMA-29）与苯乙烯-4-乙烯基吡啶共聚物（S4 VP-6和S4 VP-15）的络合行为。这种络合作用归因于不同聚合物链之间通过氢键的强分子间相互作用的存在。单一的玻璃化转变温度，中间的两个纯共聚物SMA-29和S4 VP-15，得到与每个组合物的混合物时，THF或丁-2-酮被用作共同的溶剂。结果表明，这种复合物的形成强烈地依赖于溶剂的性质和相互作用物种的含量。复合物的形成在THF中被抑制，因为后者与SMA相互作用的重要能力。这些共混物的组分之间的相互作用的定量分析进行了FTIR光谱。© 2005 Wiley Periodicals，Inc.应用聚合物科学杂志98：806-811，2005
The complexation behavior between poly(styrene-co-methacrylic acid) of different compositions (SMA-12 or SMA-29) and poly(styrene-co-4-vinylpyridine) (S4VP-6 or S4VP-15) was studied by viscometry and differential scanning calorimetry using tetrahydrofuran (THF) and butan-2-one as solvents. This complexation is attributed to the presence of strong intermolecular interactions between the different polymer chains by hydrogen bonding. A single glass-transition temperature, intermediate between those of the two pure copolymers SMA-29 and S4VP-15, was obtained with each composition of the mixture when THF or butan-2-one is used as a common solvent. The obtained results showed that the formation of such complexes depends strongly on the nature of the solvent and the contents of the interacting species. The complex formation is inhibited in THF because of the important ability of this latter to interact with the SMA. A quantitative analysis of the interactions between the constituents of these blends was carried out by FTIR spectroscopy. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 98: 806–811, 2005
