The effect of rare earth butadiene rubber structure on properties under different catalysts
To investigate the effect of the structure of rare earth butadiene rubber on its performance under different catalyst systems,data comparison was conducted on the properties of raw rubber and vulcanized rubber,while only changing themain catalyst andkeeping the other by-products,antioxidants,and viscosity reducers unchanged.The influence of cis content on the properties of rare earth butadiene rubber under various catalyst systems was analyzed,And the degree to which the structure of rare earth butadiene rubber in threemain catalyst systems affects the properties of raw rubber and vulcanized rubber.The results indicate that when using the Ⅱ catalyst system,attention should be paid to the influence of structure on the properties of raw rubber,and when using the Ⅲ catalyst system,attention should be paid to the influence of structure on the properties of vulcanized rubber.The rubber processing performance of the I catalyst system is worse than that of the Ⅱ and Ⅲ catalyst systems.
