POLYMERIZATION OF VINYLIDENEFLUORIDE (VF2) IN A SUPERCRITICAL FLUID MEDIUM

標題: POLYMERIZATION OF VINYLIDENEFLUORIDE (VF2) IN A SUPERCRITICAL FLUID MEDIUM

*Abstract: This invention relates generally to novel fluoropolymers and methods of polymerizing fluoromonomers in a supercritical fluid reaction medium involving CO2 or similarly functioning fluid, to obtain a high yield of novel and inherently pure fluoropolymers with high average molecular weights with unimodal molecular weight distributions and of gel-free free-flowing powder form. POTENTIAL AREAS OF APPLICATIONS: PVDF manufacture.MAIN ADVANTAGES OF INVENTION: Very high molecular weight PVDF, greater than 1,000,000; Longer molecules than are possible with other processes; Length of molecules is controllable; Uses environmentally friendly process.STATE OF DEVELOPMENT: Demonstrated on laboratory scale.FURTHER R&D REQUIRED: Need to demonstrate in larger scale plant.
