随着科学技术的发展,特别是空间技术的发展,愈来愈迫切需要具有耐高低温、高强度、耐辐照、抗化学腐蚀、高度绝缘等综合性能的材料。一般有饥高分子材料具有容易加工的特点,但在耐高温、耐腐蚀等方面已渐不能满足要求;无机高分子材料,虽显示出优良的高温特性,但不易加工。作为提高高分子材料性能的途径之一,是从结构上综合两者的优点,在无机链上引入有机基团,赋予无机高分子以可塑性;在有机链上引进无机结构,使有机高分子兼有无机高 With the development of science and technology, especially the development of space technology, there is an ever-increasing demand for materials that have a combination of high and low temperature resistance, high strength, radiation resistance, chemical resistance and high insulation. Usually there are hungry macromolecular materials with easy processing characteristics, but in the high temperature, corrosion resistance and other aspects of the gradual can not meet the requirements; inorganic polymer materials, although it shows excellent high temperature properties, but not easy processing. As one of the ways to improve the performance of polymer materials, it is to synthesize the advantages of both in the structure and to introduce organic groups into the inorganic chain to give the inorganic polymer plasticity. Inorganic structure is introduced into the organic chain to make the organic polymer both There is inorganic high
