钕系聚丁二烯橡胶中试技术开发

<正>稀土顺丁橡胶(NdBR)是以稀土(钕系)催化剂聚合丁二烯合成的一种高顺式-1,4-结构的聚丁二烯橡胶,因其立构规整性高,1,2结构含量低及线性结构好,拉伸时结晶度高,而表现出优于传统钛、钴、镍系聚丁二烯橡胶(BR)的物理性能和动态力学性

Pilot test technology development of neodymium polybutadiene rubber

RE butadiene rubber (NdBR) is a high-cis-1,4-polybutadiene rubber by rare earth (neodymium) catalyst and butadiene polymerizing. Its physical properties and dynamic mechanical properties can meet the demand for high performance radial tires. It has the best application value and the fastest growth rate in recent years. In China, there's no stable volume of NdBR product currently. Sinopec Beijing Yanshan Company unites with Beijing Chemical University and Materials Research and Test Center of China Rubber In...
