High speed liquid chromatographic packing and process for production thereof.

摘要

A granular crosslinked copolymer suitable as a high speed liquid chromatographic packing and especially as a gel permeation chromatographic packing is disclosed. In a preferred embodiment of the invention the packing is a copolymer essentially consisting of (I) units of at least one vinyl alcohol, (II) units of at least one vinyl ester of a carboxylic acid and (III) units of at least one crosslinking monomer having an isocyanurate ring, the ratio of the units (I) to the units (II) in the copolymer being within the range satisfying the following equation: about 0.4
