Polymers From Renewable Resources

For many years, IAM has developed a chemistry based on sustainable development (biodegradable polymers, polymer recycling, agro-resources…).

In 2007, the commitment of IAM in a chemistry for sustainable development increased with the creation of a topic dedicated to the synthesis of “Biobased Polymers and Composites”, the participation as a founding member in Carnot Institute "Chemistry, Environment and Sustainable Development (CED2)" and ChemSuD Chair " European Chemistry Chair for a Sustainable Development".

This “Biobased Polymers and Composites” topics focuses on a chemistry based on the use of renewable resources for the synthesis of reaction intermediates, biobased polymers and additives (surfactants, plasticizing agents) to reduce environmental impacts. Its objective is also to substitute hazardous compounds for human and environment (bisphenol A, isocyanates, dipentene…) by non-hazardous compounds.

Skills of the topic :

  • Transformation, biotransformation and depolymerization : bio-derivated polymers, vegetable oils and derivatives
  • Synthesis of biobased reaction intermediates and polymerization
  • Rheology assisted polymerization
  • Elaboration of binders, coatings, dense and porous materials, composites…

Resources from biomass :

  • Vegetable oils, glycerin and derivatives
  • Polysaccharides (sorbitol, chitosan…)
  • Vegetable proteins (gluten…)
  • Tannins, lignins…
  • Natural fibers : hemp, flax, bagasse…

Thus, new access routes to biobased epoxy resins based on tannins from by-products of the forestry and viniculture, were developed. In addition, our team developed new reactive functional intermediates from vegetable oils and fatty acids bearing functions such as amines, alcohols or acids. Biobased epoxy composites with natural fibers for the building and transportation have also been performed. Our team has also developed bio-derivated polyurethanes without isocyanates (NISO) for binders and coatings.

These works are carried out in partnerships with national and international companies (SMEs and large groups), with funding from the Region LR, ANR or the FUI.

In 2010 we notably received the Award of the Innovative Techniques for the Environment at Pollutec.
