U Minn researchers develop bio-based elastomers from recoverable methyl valerolactone; tires, gaskets, seals, etc.

April 18, 2017

Researchers at the University of Minnesota have developed and demonstrated at laboratory scale a novel process to synthesize low-cost, polymeric valerolactones with tunable mechanical properties and low glass transition temperatures.

The glass transition temperature is the temperature region in which a polymer transitions from a hard, glassy material to a soft, rubbery material. In other words, when the polymer is cooled below the glass transition temperature, it becomes hard and brittle. The low glass transition temperature allows these polymers to be used at lower temperatures than other biodegradable polymers; applications could include tires, gaskets, seals adhesive, sealant and damping products.
