摘要
用二氧化钛纳米晶作为催化剂对马来酰亚胺进行非均相聚合反应。单体和聚合物的结构用 I R、1 H N M R及13 C N M R 进行表征,并用 T G D T A 研究其热性能。实验结果表明,纳米晶二氧化钛能催化非均相马来酰亚胺的聚合反应。本工作为纳米晶在马来酰亚胺中提供其它应用。
Nanocrystalline materials have many specific properties. In this paper, polymerization of maleimides in a heterogeneous system was studied using nanocrystalline titatium dioxide as catalyst. The structures of the monomers and polymers were characterized by proton and carbon 13 nuclear magnetic resonance and infra red spectroscopy, and their thermal behaviour by thermogravimetric analysis and dynamic thermal analysis. In addition, the experimental results show that nanocrystalline titanium dioxide can be lead to the catalytic polymerization of maleimides in the hetrogenneous system. This work provide other application of nanocrystalline compounds in the maleimide studies.
