摘要
用红外光谱和凝胶色谱联用技术研究了软段为聚酯和聚醚的混合型聚氨酯弹性体的化学组成,提出其化学组成为嵌段共聚高分子材料,而非共混型高分子材料,并用核磁共振和粘弹谱进行了验证。
In this paper,the IR spectra and GPC method are used to study the chemical component of ester/ether polyurethane. Is is found that the component of this material is segmentcopolymer and not mixedpolymer.This conclusion is supported by the results of NMR and its visoelastic behavior.
