顺丁橡胶的链结构与其溶液性质和物理性能有密切关系,凝胶的存在往往影响加工和使用性能。付里叶变换红外光谱技术的发展使我们有可能考察顺丁分子链微结构与分子量的关系,研究凝胶与线性分子链结构的差别。 实验选用燕山石化公司胜利化工厂及应化所与该厂合作聚合的样品(分别以SY和YH表示),以及日本的BR01和一种美国样品。样品以甲苯为溶剂。甲醇为沉淀剂进行沉淀分级、
Butadiene rubber chain structure and its solution properties and physical properties are closely related to the existence of the gel often affect the processing and use performance. The development of Fourier transform infrared spectroscopy has made it possible to investigate the relationship between the molecular structure and the microstructure of butadiene molecular chains and to study the differences between gel and linear molecular chains. The experiment selected Yanshan Petrochemical Company Shengli Chemical Plant and the Institute should cooperate with the polymerization of the sample (SY and YH, respectively), and Japan’s BR01 and a sample of the United States. The sample is toluene. Methanol precipitant for precipitation classification,
