硫黄调节型氯丁橡胶门尼粘度控制的研究进展

Research Progress of Mooney Viscosity Control of Sulfur Modified CR

介绍硫黄调节型氯丁橡胶(CR)门尼粘度影响因素和断链研究状况。通过控制硫黄和调节剂用量、聚合体系和断链体系p H值、聚合温度和断链温度、单体纯度,以及采用适合的断链剂,可以有效控制硫黄调节型CR门尼粘度及其稳定性。

The factors inlfuencing the Mooney viscosity of sulfur modiifed CR compound are reviewed and the research progress on the chain scission is introduced in this paper. In order to effectively control the Mooney viscosity, it is recommended to precisely control the amounts of sulfur and chain scission agent, pH values of the polymerization system and chain scission system, polymerization temperature, chain scission temperature and monomer purity, and use appropriate type of chain scission agent.
