  • Vitrimers containing additives
    Patent number: 12398264
    Abstract: Covalent network polymers that include one or more of a cure rate modifying (CRM) additive, a tack modifying additive, a flame retardant additive, a physical additive, and a viscosity modifying additive allow the viscosity, pot life, tackiness and safety of chemical mixtures and products to be tailored without sacrificing the mechanical properties or reprocessability of the final vitrimers. Use of additives also enables previously infeasible manufacturing techniques.
    Type: Grant
