一、高分子化学一般介绍高分子化学是一门新兴的科学。对一般人说来,比较生疏。但是高分子化合物,则触目皆是。从生命的基本物质—蛋白质一起,到我们日常衣食住行,所接触的事物大多数都是高分子化合物。无机的如各种金属、石英、玻璃、矽酸盐、许多矿物等;有机的如蛋白质、淀粉、纤维素、橡胶、树脂等,都是属于高分子范围。人工合成的有机高分子化合物,如酚醛树脂之类,现在也逐渐成为日常生活及各种工业的必需品了。 (一)高分子化合物的特点高分子化合物和一般低分子化合物所不同的是它们的分子量。第一,高分子的分子量很高。低分子化合物的分子量一般都在一千以下,一千到二千的很少见,二千以上的可以说是没有。可是在高分子化合物中,如天然橡胶分子量可以从几万到四、五十万,淀粉到二、三十万,纤维素可以到二百万,蛋白质 First, the general introduction of polymer chemistry Polymer chemistry is a new science. To the average person, relatively unfamiliar. But macromolecular compounds, then all visible. From the basic substance of life - protein, to our daily necessities of life, most of the things we touch are polymer compounds. Inorganic such as various metals, quartz, glass, silicate, many minerals, etc .; organic such as protein, starch, cellulose, rubber, resin, etc., belong to the polymer range. Synthetic organic macromolecular compounds, such as phenolic resin, are now gradually becoming a necessity in daily life and various industries. (A) the characteristics of polymer compounds Polymer compounds and general low molecular weight compounds are different from their molecular weight. First, the high molecular weight of the polymer. The molecular weight of low molecular weight compounds are generally less than a thousand, a thousand to two thousand are rare, more than two thousand can be said to be no. But in the polymer compounds, such as natural rubber molecular weight can be tens of thousands to four, five hundred thousand, two to three hundred thousand starch, cellulose can be two million, protein
