研究了双酚A聚羟基醚（苯氧基）与聚N-甲基-N-乙烯基乙酰胺（PMVAc）、聚N，N-二甲基丙烯酰胺（PDMA）和聚（2-乙基-2-恶唑啉）（PEOx）三种异构体叔酰胺聚合物的络合行为。在整个进料组成范围内，苯氧基与PMVAc和PDMA从四氢呋喃溶液形成共聚体复合物。然而，络合不发生之间的苯氧基和PEOx从THF溶液中，表明较弱的分子间缔合的苯氧基/PEOx的共混物比那些在苯氧基/PMVAc和苯氧基/PDMA共混物。当使用N，N-二甲基甲酰胺作为溶剂时，在苯氧基和所有三种叔酰胺聚合物之间仅形成可混溶的共混物。红外光谱研究提供了苯氧基中的羟基和叔酰胺聚合物中的羰基之间的分子间氢键的证据。与三种叔酰胺聚合物氢键键合的苯氧基羟基的频移按PMVAc -> PDMA -> PEOx的顺序减小。版权所有（C）1996 Elsevier Science Ltd.
The complexation behaviour between poly(hydroxyether of bisphenol-A) (phenoxy) and three isomeric tertiary amide polymers, namely poly(N-methyl-N-vinylacetamide) (PMVAc), poly(N,N-dimethylacrylamide) (PDMA) and poly(2-ethyl-2-oxazoline) (PEOx), has been studied. Phenoxy forms interpolymer complexes with PMVAc and PDMA from tetrahydrofuran solutions over the entire feed composition range. However, complexation does not occur between phenoxy and PEOx from THF solutions, indicating a weaker intermolecular association in the phenoxy/PEOx blends than those in the phenoxy/PMVAc and phenoxy/PDMA blends. When using N,N-dimethylformamide as the solvent, only miscible blends are formed between phenoxy and all three tertiary amide polymers. Infra-red spectroscopic studies provide evidence of intermolecular hydrogen bonding between the hydroxyl groups in phenoxy and the carbonyl groups in tertiary amide polymers. The frequency shifts for the phenoxy hydroxyl group hydrogen bonded to the three tertiary amide polymers decrease in the order of PMVAc --> PDMA --> PEOx. Copyright (C) 1996 Elsevier Science Ltd.
