摘要
利用^(13)C核磁共振法研究了酚酞/双酚T型聚芳醚砜共聚物((PP/Bis-T)PES)的序列结构,分析了将双酚T单元引入酚酞型聚芳醚砜(PES-C)聚合物分子中对其酚酞单元的核磁共振谱的影响,并证实了(PP/BiS-T)PES属于无规共聚物。
The results investigated the sequence structure of poly ( ary-thene ether sulfone ) copolymer of phenolphthalein/4, 4'-thiodiphenol type( (PP/Bis)PES ) using13C-NMR method are described. The influence of 4, 4'-thiodiphenol monomer on13C-NRM spectra of phenoph thalein unit has been analysed as addition of Bis-T to poly ( arylene ether sulfone) of phe-nolphthalein type.The results also proved that ( (PP/Bis-T ) PES ) belongs to random conolvmer
