Electrocatalytic grafting and modification of polyvinylchlorides and chloroparaffins

The Need

Polyvinylchloride (PVC) is a widely used plastic, but its inherent limitations—brittleness, thermal instability, and poor shear strength—pose significant challenges for diverse applications, from medical packaging to construction. Conventional PVC modification relies on high loadings of plasticizers and stabilizers, hindering recyclability and environmental safety. The need for a breakthrough technology to overcome these limitations and provide controlled macromolecular properties in PVC is evident.

The Technology

Our groundbreaking technology enables on-polymer bond functionalization of PVC, allowing precise control over its physical properties. Through selective activation and functionalization of C—Cl bonds, our method eliminates the reliance on non-covalent additives, providing a sustainable and controlled approach to PVC modification. The use of electrosynthesis, merging with metal-catalyzed organic synthesis, allows for unprecedented selective functionalization of inert C—Cl bonds under mild conditions.
