Preparation of Heterobimetallic Catalysts

Polyolefins are the largest volume polymers in the plastics industry. However, enhanced functional polyolefins with well defined compositions and morphology are difficult to synthesize using current free radical-based methods. The UH method uses late transition metal catalysts with interchangeable Lewis acids to increase reaction rates, which can lower production costs and allow operations at industrially relevant temperatures. Latest UH experimental results indicate catalyst productivity and activity that are several times greater than those achieved by conventional catalysts. 

Applications

  • Catalysts for customized functional materials as water proof materials in roofs, shoes and in acrylics, epoxies. 
  • Flexible and rigid packaging for films, sheets, and oxygen barrier packaging for long shelf life of food.

Problem Addressed

  • No need for high cost palladium as polymerization catalysts.
  • No need to synthetically modify catalyst platform to obtain different polymer materials.

Competitive Advantages

  • "Tuning" of polymerization properties such as recreation rates, polymer branching and molecular weight.
  • The metal catalysts are compatible with a wide range of secondary cations, such as those of the s-, d-, and f-block elements.
