NineSigma, on behalf of a global materials company, invites proposals for expertise, technology, or methods to solve a chemical interaction that causes yellowing of a liquid prepolymer blend.
NineSigma’s client is working with a mixture of hydrofluoro-olefin monomer and a blend of alkyl vinyl ethers, some of which have pendant hydroxy groups (such as 4-hydroxybutyl vinyl ether). The prepolymer mixture is a high-solids, viscous liquid diluted slightly in butyl acetate. Subjecting this initially colorless, or lightly colored (yellowish), mixture to continuous heat, up to 95 °C, produces noticeable yellowing (several ΔE) in as little as 4-5 days. The client observes yellowing in mixtures that range from 35 wt% to 70 wt% prepolymer in solvent.
NineSigma’s client seeks to understand the yellowing phenomenon. We encourage you to respond to this request if you have knowledge, methods, or technology which can eliminate the yellowing in this prepolymer blend.
Key Success Criteria
The goal is to:
Eliminate yellowing interaction in a prepolymer blend of hydrofluoro-olefin monomer with alkyl vinyl ethers
Maintain the physical performance characteristics of the blend
Utilize methods which can be implemented in large scale manufacturing
Be cost effective at commercial scale
Items to be Submitted
