Recycles Polymers into More Useful Polymers, Saving Money on Production Costs

These chemical reactions convert naturally occurring oligomers and polymers into functionalized materials for commercial use. This technology recycles the polymer components of chemicals such as polybutadiene, polyisoprene and naturally occurring oils, and converts them into other useful synthetic polymers, including polyamides and polyesters. Because the starting materials are recycled and readily available, the technology created by University of Florida researchers produces a less expensive, solventless, sustainable and ecofriendly way to yield more functional commercial polymers with multiple market applications, including plastics, rubbers and polymers.

Application

Chemical reactions from recycled and inexpensive starting materials to produce polyesters and polyamides

Advantages

  • Uses readily available starting materials, saving money on production costs
  • Solventless process results in high yield throughput
  • Allows for polymer recycling, making the technology sustainable and ecofriendly
  • Has many applications and may be incorporated into several industries, creating multiple market opportunities
  • Uses naturally occurring oils, increasing opportunities to produce more functional substances

Technology

Researchers at the University of Florida have developed a technology that uses metathesis polymerization reactions with acrylates, compounds with a vinyl group adjacent to a carbonyl, to convert chemicals such as polybutadiene, polyisoprene and naturally occurring oils into functional oligomers and polymers, including polyamides and polyesters. The process does not require the use of solvents and could be applied to other materials, such as castor oil or linseed oil as starting materials for commercial polymers.
