摘要
The invention relates to a process for preparing a poly (2-hydroxypropyl acrylate) cross-linked with divinyl benzene phase HPLC on activated silica-bound, in which the reaction of toluene with dietoxymetylvinylsilanom initiate a vinyl group and who-ROM, followed by reaction with trimethylchlorosilane blocked reactive free silanols, and thus the modified silica gel treated with a mixture of 2-hydroxypropyl methacrylate and divinylbenzene in the presence of a radical polymerization initiator at a temperature of 100 to 120 � C for 18-24 hours under stirring and in the presence of a suitable solvent, while at the same time-go via polymerization of methacrylate and divinylbenzene cross-linking. The invention relates to the use of poly (2-hydroxypropyl acrylate) crosslinked with divinylbenzene phase chromatography, bound to the activated silica gel for separation Biel-leguminous.
