Monomer Recovery from Biobased Polyurethane
Polyurethane Synthesis from Biodegradable Polyesterol PMVLBiobased and chemically recyclable polyurethane (PU) offers a greener alternative to petroleum derived polyols used in the synthesis of thermoplastic polyurethanes, flexible foams and elastomers. A new technique uses renewable and degradable β-methyl-δ-valerolactone (MVL), to create a bio-based PMVL (poly β-methyl-δ-valerolactone) polyol with similar mechanical properties and performance of petroleum-derived PU.MVL Monomer Recovery from Polyurethane FoamAnother innovative aspect of this technology is the ability to recycle PMVL foams to recover MVL monomer in high purity and yield. Recycling foam to monomer (instead of polyol) allows the recovered monomer to be polymerized into polyols of any desired molecular weight and functionality. Furthermore, solvent-free, room temperature polymerization of the recovered MVL can be used to synthesize PMVL.Recycling PolyurethaneCurrent non-degradable, petroleum-derived polyurethane products create a massive waste management problem. Biobased and chemically recyclable polyurethanes, together with the unique MVL recycling strategy, bypasses many of the technical challenges that plague chemical recycling of polyurethanes.BENEFITS AND FEATURES:Biobased and chemically recyclableSimilar mechanical properties and performance of petroleum-derived PURecycle PMVL foams to recover MVL monomerAPPLICATIONS:Biobased and chemically recyclable polyurethane synthesisPMVL synthesisMVL recoveryPMVL recyclingPhase of Development - Proof of concept
