1.高分子性貭的特点 人类使用高分子物貭的历史已經很久,例如蚕絲早在古代就开始使用,然而对它的物理性质和化学性貭却很少研究。近几十年来,高分子的应用迅速增长并遍及許多方面。现在所使用的高分子,在天然产物中,除蚕絲外,尚有棉花、麻、羊毛、橡胶、皮革、胶等,也有从人工合成制得的材料,如人造纤維、人造皮革、人造橡胶等可以用来代替天然产物,此外高分子物貭的溶液还可以用来做油漆、胶等。仅从上面所列举的材料而言,高分子物貭的重要性已是不必多說的了,何况組成动物組織单元的蛋白貭也是高分子,因此高分子不仅与化学与工业有关,而且
1. The characteristics of macromolecule 貭 human use of macromolecules 貭 history has long been, for example, silk began to use in ancient times, but its physical properties and chemical 貭 rarely studied. In recent decades, the use of polymers has grown rapidly and in many ways. Now used in the natural products, in addition to silk, there are cotton, linen, wool, rubber, leather, plastic, etc., but also from synthetic materials, such as man-made fibers, artificial leather, synthetic rubber, etc. Can be used to replace natural products, in addition to polymer solution can also be used to make paint, glue and so on. Only from the above list of materials, the importance of polymer material is not to say, not to mention the composition of animal tissue unit protein is also a high molecular polymer, so not only with the polymer and chemical industry, and
