| 摘 要： | <正> 一般说,硅氮键对水不稳定,因此聚硅氨烷尽管具有较好的耐热性,但是仍未得到应用。等指出,硅原子或氮原子上带有较大的空间位阻的基团后,如苯基等,可以提高硅氨烷的水解稳定性,取代基的电子效应对其水解稳定性也有影响。Fink发现

| Abstract: | The hydrolytic stability of polyorganosiloxanes containing cyclodisilazane in the backbone and their monomer were studded. The phenyl substitution on silicon was observed to increase the hydrolytic stability of silicon-nitrogen bond in the cyclodisilazane. However, it was found that siloxane segment bonded cyclodisilazane could increae the hydrolytic stabilyty of silicon-nitrogen bond, while the macromolecular structure could give substantial increase in the hydrolytic stability. Hence, the polymers obtained are very stable to water. |
