Hydrogenative depolymerization of silicon-modified polyureas

Silicon-modified polyureas were depolymerized by hydrogenation in the presence of Ru and Mn catalysts. Yields of up to 84% of the aliphatic diamine and 81% of silicon-containing diamine were achieved with a commercially available PNP-Ru catalyst.

Automated summary

Silicon-modified polyureas were successfully depolymerized using hydrogenation with Ru and Mn catalysts, resulting in high yields of aliphatic diamine and silicon-containing diamine.
