摘要
以线型醚基聚氨酯为研究对象,应用FTIR及减法光谱技术考察了水分子与聚氨酯体系中极性基团的作用,给出水分子与羰基结合的直接证据,并进一步指出了水分子的结合对醚键、酰胺结构以及碳氢链结构造成的影响。这一结果表明,FTIR光谱法可以成为研究高分子体系的水化机理的重要手段。
The interaction between water molecules and the polar groups in linear polyether urethane was studied by FTIR and subtraction spectroscopy technique. Direct proofs of the combining of water molecule and carbonyl group were obtained. The reorganizations of the ether linkage, carbamate, and carlton-hydrogen chain after hydration were also obsea＇ved. These results suggest that the FTIR and subtraction spectroscopy technique could be a useful tool to investigate the hydration mechanism of polymer materials.
