Process for making fluorinated polymer adsorbent particles

摘要

A process to make particles by anaerobic reaction of a water-insoluble solution of organic compounds comprising (a) a monomer selected from C2-4 alkylene glycol esters of a C3-6 acrylic acid and a divinyl benzene; (b) a polyfluorinated vinyl monomer; (c) a monomer selected from acrylic acid, methacrylic acid and esters thereof; (d) a free radical initiator; and (e) a water-insoluble, organic solvent-soluble porogenic material, the weight ratio of comonomers (a) plus (b) plus (c) to the porogenic material being from 0.5:1 to 2:1. The adsorbent particles produced by the process are useful in carrying out chromatographic separations, or in the production of medical devices.
