MICROSPHERES OF THERMALLY PROCESSED TETRAFLUOROETHYLENE COPOLYMER Russian patent published in 2006 - IPC C08F6/22 C08F214/26

Abstract RU 2271366 C2

FIELD: polymer materials.

SUBSTANCE: invention is dealing, in particular, with thermally processed tetrafluoroethylene copolymers having predominantly spherical shape for at least 95 wt % of material. Median microsphere size lies within a range of 25 μm to 2 mm and bulk density between 0.5 and 1.1 g/cm³. Invention also concerns coagulation apparatus and microsphere preparation process.

EFFECT: enabled preparation microspheres of thermally processed tetrafluoroethylene copolymer characterized by specified morphology, controlled size, and improved fluidity.
