不少植物通过嫁接,可以改良品种。同样,高分子化合物通过“嫁接”,也可以获得较全面的优异性能,适应生产发展需要。近几十年来,人们就已制得了不少合成材料——高聚物(高分子化合物)。但是,它们都有这样或那样的缺点,不能满足现代生产和科学技术发展的要求。能不能制得性能比较全面的新型合成材料呢?经过研究,人们发现,高聚物的分子大多数是长链状的,它的性能主要决定于长链的组成和结构。 Many plants can be improved by grafting. Similarly, through the “grafting” of polymer compounds, it is also possible to obtain more comprehensive excellent performance and adapt to the needs of production development. In recent decades, people have made a lot of synthetic materials - polymers (polymer compounds). However, they all have one or more shortcomings and cannot meet the requirements of modern production and the development of science and technology. Can we obtain new synthetic materials with relatively full performance? After research, it was found that most of the molecules of polymers are long chains, and its properties are mainly determined by the composition and structure of long chains.
