AI Technical Summary

Technical Problem

Silane functionalized polymers are prone to hydrolysis and condensation upon exposure to water, heat, and work, resulting in increased coupling and Mooney viscosity, thus limiting their availability in target applications.

Method used

After the silane linkage and polymerization is completed, alkoxysilane is added to the polymer slurry to control hydrolysis and condensation, thereby adjusting the coupling of the polymer and final Mooney viscosity.

Benefits of technology

Through this method, the hydrolysis and condensation of the polymer can be effectively controlled, and the coupling process can be delayed, thereby maintaining the functionality and performance of the polymer and expanding its application range in multiple industries.
