China Produces HighâPurity âArtificialâLungâ Monomer at Pilot Scale, Easing Dependence on Imports
A Dalian UniversityâSinopec team has produced 4âmethylâ1âpentene (4M1P) at 99.3% purity in a hundredâton pilot run, a milestone for domestic manufacture of poly(4âmethylâ1âpentene) used in ECMO membranes. The result could reduce reliance on imports for a critical medicalâdevice input, though commercial scaleâup and regulatory steps remain.
