After modification of the porous support

摘要

The method for modification after the porous polymeric polysaccharide support comprising a double bond unreacted one or more, the present invention, grafting compounds of at least one polymeric support the method includes initiating a free radical reaction in the mixture obtained and contacting a liquid phase comprising, at which contain hetero atoms, one or more optionally, the grafting compound is a cyclic or linear, in which consisting of two double bonds as reactive groups attached to the carbon chain, to a method. Preferred grafting compound is a hydroxy vinyl ether or vinyl ether. And polymeric substrate is post-modified by the method according to the present invention also, for example in chromatography, the invention encompasses the use of such supports.
