制备了含聚 1,3 二氧戊环链段具有pH敏感性的可解体聚合物凝胶网络 ,网络可在水中及有机溶剂中溶胀 ,且由聚 1,3 二氧戊环构成的水凝胶成分可以在酸性介质中降解 ,使网络解体 .利用红外光谱、色 质联谱等分析手段对聚合物凝胶网络进行了表征 .通过对降解产物的分析 ,一方面证实了降解现象的存在 ,另一方面证实了聚合反应机理 A pH-sensitive, disintegrable polymer gel network containing poly 1,3-dioxolane segments was prepared, the network was swollen in water and in an organic solvent, and a hydrogel consisting of poly-1,3-dioxolane The gel components can be degraded in acid medium to disintegrate the network.The polymer gel network is characterized by means of infrared spectroscopy, chromatographic mass spectrometry, etc. The degradation products are confirmed by the analysis of the degradation products, On the other hand, it confirmed the polymerization mechanism
