METHODS OF MAKING POROUS DEVICES FROM MONODISPERSE POPULATIONS OF POLYARYLKETONE OR POLYARYLTHIOETHERKETONE PARTICLES

The invention provides methods for making porous devices from substantially monodisperse populations of substantially spherical particles of polyarylketone polymers or of thio-analogues of such polymers, of selected sizes. The porous devices allow greater control of porosity than previously availabl...

Beschreibung
Zusammenfassung:	The invention provides methods for making porous devices from substantially monodisperse populations of substantially spherical particles of polyarylketone polymers or of thio-analogues of such polymers, of selected sizes. The porous devices allow greater control of porosity than previously available porous devices. In some embodiments, the porous devices are frits, filters, membranes or monoliths. L'invention concerne des procédés de fabrication de dispositifs poreux à partir de populations sensiblement monodispersées de particules sensiblement sphériques de polymères polyarylcétone ou de thio-analogues de tels polymères, de tailles sélectionnées. Les dispositifs poreux permettent une plus grande maîtrise de la porosité que les dispositifs poreux précédemment disponibles. Dans certains modes de réalisation, les dispositifs poreux sont des frittes, des filtres, des membranes ou des monolithes.
