Abstract
The invention relates to partially hydrophilic, non-ionic crosslinked copolymers. These copolymers consist of a crosslinked hydrophobic backbone having a high mechanical strength, and of non-ionic hydrophilic chains grafted selectively onto the backbone. The copolymers are useful for size exclusion chromatography in an aqueous medium.
