A French Technology Transfer Office offers new functionalized polyolefins for utilisation in performance materials for licensing
A French Technology Transfer Office (TTO) offers new functionalized polyolefins for utilisation in performance materials. These new specialty polyolefins allow the combination of commodity polymer advantages (low cost, low toxicity) with the added value provided by the new functionalities. A French SME is working with the TTO to scale-up the process. The TTO is looking for industrials interested in the technology for licensing.
The TTO and a French SME are currently working on the scale-up of the process. Industrials interested in the exploitation of the technology are sought for licensing.
*Market challenges Thermoplastic polyolefins like polyethylene are unreactive, non-functional materials. The introduction of functional and or reactive groups on polyolefins is a challenge to produce building blocks for further polymerisation and new specialty materials , for applications in cosmetics, plastics, adhesives, coatings, chemistry, etc. *State of the art The actual challenges resides in the lack of reactivity of polyolefins, limiting the functionalisation potential, and on the production costs associated with classical methods. Functional polyolefins are classically obtained by post-polymerisation, requiring a longer synthetic route, or by living-polymerisation, requiring one catalyst per polymer chain and thus inducing larger production costs. *Proposed technology New polyethylene building blocks with end or lateral functionalities have been developed with an innovative process allowing the introduction of multiple functionalities in a one-pot reaction. The polymerisation process is catalytic, presenting the advantage of producing a large number of chains per catalyst, for a reduced cost production. The process has been scaled-up at kilogram scale with tunable molar mass control. These new specialty polyolefins allow the combination of commodity polymer advantages (low cost, low toxicity) with the added value provided by the new functionalities. The versatility of functions developed allows the introduction of new physico-chemical properties to materials: non-polarity, crystallinity or thermal properties can thus be introduced on apparently incompatible materials. *Organisation This new technology is carried by a French Trechnology Transfer Office (TTO) working with researchers from the local university. *Desired cooperation Partners from chemical industry are sought for license agreements. Within the agreements there are opportunities for further development and commercial use.

How it works
- Tell us about yourself
- We’ll discuss with you
- We put the right partners in touch
EEN help you find the right partner, rather than you going it alone.
Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.
These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.
Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
First we need to check you’re human.
