一、高分子材料的发展高分子科学的历史虽然不很长,在三十年代才建立起高分子长链的概念。但是由于高分子材料的种种优点,符合工业上和日常生活上的需要,所以发展迅速,现在的生产规模,在体积上早已超过金属产量的总和。 First, the development of polymer materials Although the history of polymer science is not very long, only in the thirties to establish the concept of polymer chains. However, due to the advantages of polymer materials, in line with the needs of industry and daily life, so the rapid development of the current scale of production, the volume has already exceeded the sum of metal production.
