研究了氨基噻吩在DMF/H2O混合物中对PVC增塑膜的化学改性。利用拉曼光谱和FTIR-ATR测定了改性程度和改性基团在膜内的分布。在无反应物的对照反应中，采用H-1核磁共振光谱和拉曼光谱分析了增塑剂（邻苯二甲酸双-2-乙基己酯，DOP）在反应过程中的漂白量和二甲甲酰胺（DMF）渗透到膜中的量。将改性反应的反应动力学和表面选择性与无增塑剂的PVC膜的相应反应进行了比较。2003爱思唯尔科学有限公司版权所有。
The chemical modification of plasticized PVC films with amino thiophenol in mixtures of DMF/H2O has been studied. The degree of modification and the distribution of modified groups within the films were determined using Raman spectroscopy and FTIR-ATR. The amounts of plasticizer (bis-2-ethylhexyl phtalate, DOP) bleached out during the reaction and the amount of dimethylformamide (DMF) penetrated into the film were analysed in control reactions without the reactant using H-1 NMR spectroscopy and Raman spectroscopy. Reaction kinetics and surface selectivity of the modification reaction were compared with the corresponding reactions of PVC films without plasticizer. (C) 2003 Elsevier Science Ltd.
