化学自从成为一门成熟的科学以来,在对自然界中小而又小的实体的追根究底方面,不再处在第一线了。但是,作为与分子关系最深的科学,化学仍然处在首要地位。它在阐明物质最常见的形式方面,在培养对常见物质的性质及其所经历的变化更广泛的鉴别方面,既有义务,又有可能。此外.化学科学必须对新技术有所帮助,也应该促使现有的技术更适合今天与明天的需要。因而,化学在文化与技术方面,起了双重的作用。在这两方面,大分子的重要性都是突出的.它的组成物质很平凡。大分子构成所有生物物质的组织,并执行生命过程所赖以实现的主要调节功能。在工业领域内,近年来看到的合成聚合物用途的飞速发展。看来肯定还会继续下去,以至于代替金属及其他的不能从更新来源所得的材料。能结合到长分子链中的分子构造花样繁多,因而所提供的可能性实际上是无限的。生命科学与聚合物工艺在未来年代所需要的有关聚合物的知识,是不扎实而有限的。所以,当务之急是取得对大分子更为深入的理解。 Since becoming a mature science, chemistry is no longer at the forefront of the search for small but small entities in nature. However, as the science and chemistry that has the deepest relations with the molecules, chemistry still remains a top priority. It is both obligatory and possible in elucidating the most common forms of matter, in developing a broader discrimination of the nature of common substances and the changes they experience. In addition, chemical science must be helpful for new technologies and should also make existing technologies more suitable for today’s and tomorrow’s needs. Thus, chemistry plays a dual role in culture and technology. The importance of the macromolecule is outstanding both ways, and its composition is very ordinary. Macromolecules make up the organization of all living things and carry out the major regulatory functions upon which the life process depends. In the industrial field, the use of synthetic polymers seen in recent years has been rapidly growing. It seems certain to continue so much that it will replace metals and other materials that can not be sourced from renewable sources. The variety of molecules that can be incorporated into long molecular chains is so diverse that the possibilities offered are virtually limitless. The knowledge of polymers that life sciences and polymer processes need in the coming years is not solidly and limitedly available. Therefore, it is imperative to get a more in-depth understanding of the great people.
