目前,高分子科学已进入一个崭新的阶段。用改变高分子链的结构形式,或者在高分子主链上加上几个特殊“基团”的方法,赋于高分子耐高温、抗低温、耐腐蚀、抗氧化以及电、磁、光、生理、催化等一系列特殊功能,可以制成各种特殊材料。如宇航需要的轻、牢、韧、耐高温、耐低温、耐辐射的材料,深潜需要的耐压、防腐、高强度的材料;火箭发射需要的体积小、能值高的燃料,等等。 At present, polymer science has entered a completely new stage. By changing the structure of the polymer chain structure, or in the polymer backbone with a few special “group” method, given the polymer high temperature, low temperature, corrosion resistance, oxidation and electrical, magnetic, optical, Physiological, catalytic and a series of special features, can be made of various special materials. Such as aerospace light, solid, tough, high temperature, low temperature, radiation-resistant materials, deep diving potential pressure, corrosion, high strength materials; rocket launch needs small, high fuel, and so on .
