Functional Polymer Products
Advanced Polymer-Supported Reagents and Catalysts for Modern Organic Synthesis
Cheminnovatix develops functional polymeric materials that combine the performance of homogeneous reagents and catalysts with the practical advantages of heterogeneous systems.
Our polymer platform enables straightforward separation, reuse and implementation in both batch and continuous-flow processes
Polymer-Supported Palladium Catalyst
Heterogeneous palladium catalysts for synthetic transformations. Palladium immobilized on functional polymer supports enables straightforward catalyst separation and provides a platform for catalyst recovery and repeated use.
Polymer-Supported Carbodiimide
Reusable coupling reagents for carboxylic acid activation. Polymer-bound carbodiimide functionality provides an efficient heterogeneous platform for the activation of carboxylic acids while simplifying reagent removal and downstream purification.
Polymer-Supported Aminopyridine
Immobilized DMAP-type organocatalysts. Polymer-supported aminopyridine catalysts combine the catalytic activity of DMAP-type nucleophilic catalysts with the advantages of an insoluble polymeric support. Immobilization facilitates catalyst separation from the reaction mixture and provides opportunities for catalyst recovery, reuse and continuous processing.

SCIENTIFIC VALIDATION
Demonstrated Stability in Repeated Use
The polymer-supported palladium catalyst was evaluated over five consecutive 16-hour aminocarbonylation cycles at 130 °C and directly benchmarked against commercial Pd EnCat® 30 NP. Under the reported recycling conditions, the polymer-supported catalyst demonstrated lower palladium leaching and improved support stability compared with commercial Pd EnCat® 30 NP.
